In the video, she said that there would probably never be a mammal discovered that can complete parthenogenesis, but then the explanation clearly stated that this was why placental mammals specifically couldn't do parthenogenesis. Does this mean that marsupials or monotremes could possibly complete parthenogenesis, or is there a different explanation for that being impossible?

The word "Parthenon" originates from ancient Greek and is derived from the Greek word Parthenṓn, which means "virgin's apartment" or "maiden's quarters." The Parthenon is a famous ancient temple located on the Athenian Acropolis in Greece, dedicated to the goddess Athena, whom the Greeks often referred to as "Parthenos" (meaning "virgin" or "maiden"). The connection between the Parthenon and the concept of virginity stems from its association with the goddess Athena, who was regarded as a virgin deity. The temple served as a monumental shrine to Athena Parthenos, embodying her role as a maiden goddess and symbolizing her purity and wisdom.

Wait... if female bees kill and eat diploid males, does that mean the bees can tell diploid males apart from haploid males?

[@LawTaranis]

If the DNA codes for a pheromone, it would probably change the form of the pheromones if there are extra copies. Nature is wild.

[@ellie8272]

This likely evolved because a haploid male shares 100% of his dna with his queen, while his children would only share 50%, making them loyal to the hive over their own young. Diploid males share equal dna with their mother and their young, making them potential traitors if they left to breed with an outside female

I just spent all morning researching the self-cloning (parthenogenesis) Marbled Crayfish to win an argument with my brother… then this pops up. The argument? That these were the crayfish we used to catch in West GA back in the ‘80s and early ‘90s. Had to show that they aren’t yet pervasive except in the streams they’ve been introduced to by humans since being discovered 1995. Obviously, they could exist naturally in one stream somewhere if their origin was not in captivity but it’s not likely to be that one.

[@abtinbarzin8369]

Haven't done much research into it, but I have read some of the overviews written about it: correct me if I'm wrong, but wasn't it linked back to the German pet trade? If so, then they had to get the animals from somewhere, and I'd assume that they were just caught and imported from the US.

[@emmettturner9452]

@@abtinbarzin8369 A German discovered them after buying “Texas Crayfish” from an American pet dealer and noticing the parthenogenesis in 1995. They weren’t even named until 2003. It very well may have come from a wild-caught population somewhere but they would have been isolated, not pervasive, and the distribution map does not even include West GA, meaning the odds that we had them as kids were very low. Because they can’t easily get from one waterway to another disconnected one, all known wild populations were introduced there by people. That said, I recall a pet shop in town that had a pregnant crayfish (eggs/young under tail). My twin brother and I were literally saving money for it when we found out there were free crayfish in the woods right behind us. :) Most were small but a few were almost lobster-sized! Before you knew it, all of our aquariums had wild-caught crayfish of all sizes… and I never saw a single adult with young. We put that money toward our saving for some Red Eared Sliders (turtles) and by the time we had enough Georgia had made it illegal to sell them due to the possibility of carrying Salmonella.

[@petersmythe6462]

I think we need to distinguish between clonal parthenogenesis and consanguinous parthenogenesis. In the case of cloning there isn't really genetic information lost at the individual level or multiplication of deleterious alleles within an individual. In the case of consanguinity, then it is almost maximally bad from the standpoint of deleterious recessives.

[@emawerna]

My weird thought is that consanguinous parthenogenesis is not about producing viable offspring but is about cleaning out the female's reproductive tract so that when a male does show up after a long absence, she maximizes her future chances of having healthy babies because she has maintained a healthy reproductive tract. It's like how human women expel period blood instead of reabsorbing it like most mammals. It is a complex evolution-backed calculus about whether it is reproductively desirous to regularly develop newer, cleaner lining at the expense of the energy required to make the new lining. If you're a fish that doesn't take care of offspring, it wouldn't matter if a cleaning process resulted in a new weak fish that swam away or not. The second-generation parthenogenesis in the video probably only happened because the aquarium was an unusually safe and secure environment. In the wild, such weak fish are probably always eaten.

[@darthphilfy]

There is only the two monotremes, the echidna and the platypus, and they get their freak on in the standard manner. Well kind of, the male echidna has a 4 headed penis and the male platypus has a 2 headed penis and barbs along the penis so he can stay inside the female whilst mating in the water. The platypus courtship is amazing to see, they play in the water in sync with each other, yet not touching until the female is ready. Then it's 10 minutes of nooky time and afterwards she ignores him and heads off to her burrow in the bank, whilst he has a rest before heading off to start courting another female for a couple of weeks before he gets another 10 minutes of happy time. Both are amazing, and beautiful. I'm fortunate to live close to a creek that is home to a few platypus and water rats and other native wildlife. I'm not so happy about the abundance of nope ropes (snakes) in the area, but they aren't bad eating if cooked properly. www.abc.net.au/news/science/2021-12-28/platypuses-and-echidnas-five-weird-things-about-them/100662846

[@Infernoraptor]

The fact that the parthenotes seem to be consistently sickly (in non-obligately parthenogenic) vertebrates is really interesting. Why would reshuffling the mom's genes result in that high of a chance of sickness? And that many KINDS of sickness? If the young aren't viable long-term, why would these animals waste so much energy making parthenotes? In addition, this issue strikes me as somewhat similar to the issues seen with clones. In short, is there something that parthenogenesis and cloning lack that sex has? (Edit: I mean, does sex do something on the cell/gene level that cloning and parthenogenesis don't have? More than just having additional gene-options)

[@lazergurka-smerlin6561]

I mean it's the same problem as inbreeding, except one million times worse

[@Appletank8]

Sex evolutionary is a way to shuffle up genes, and reduce the chances of bad, hopefully recessive genes from expressing. More shuffling increases the chance of something different to activate compared to the parent. Most of the time, a different gene does nothing. Sometimes, its worse and the offspring dies. But sometimes the offspring unlocks something more beneficial, and this increased survival rate spreads out through the population. Low genetic diversity is a problem because the chances of genetic shuffling is lower, risks of negative genes expressing is higher. If some disease hits a low diversity population, it is less likely any members of the species has happened upon a genetic quirk that increases their resistance, which is why cloned species are especially vulnerable to infection. On a side note, there's a portion of the European population that is more resistant to the bacteria that cause the Black Death. You can imagine why.

[@huldu]

I'm sure there are exceptions where something positive comes out of it and that might be it. Like laying thousands of eggs and hope that a couple survive.

[@Infernoraptor]

@Appletank8 I get that part, but this video is making it seem like parthenotes are almost guaranteed to have issues, while inbreeding doesn't cause issues as quickly. I mean, just look at the parthenote condors; there's tons of inbreeding going on and yet the parthenotes were particularly weak. (Maybe that's because they were inbred AND parthenotes?)

[@Appletank8]

@@Infernoraptor I guess that if the gene pool is healthy, a few clones won't be much of a big deal, and can add a few more bodies into the population. Like, many monarchs of Europe were inbred but it didn't immediately cause problems until later successive loops. Those female only lizards are healthy now, so a clone wouldn't necessarily come out with issues. But they would be way more vulnerable to environmental shocks.

Thank you Savannah. About your sweatshirt: Your best is pretty awesome.

[@AccidentalNinja]

I was wondering why there weren't mammilian pathenotes. Also, that's fascinating about the bees. I wonder what would happen if the diploid male managed to mate?

[@DJFracus]

Male bees do not use meiosis to make sperm because they are normally haploid, so they just give their entire chromosomes instead. So if a diploid male mated with a queen it would result in triploid females. Being triploid doesn't work for meiosis and would result in sterile queens. I think it also makes the effects of inbreeding worse, and diploid males are already a symptom of inbreeding, more inbreeding = higher chance of diploid males since it's likelier you get two copies of the same single allele out of the ~15 sex-determining gene alleles, which is what results in a diploid male.

I'm wondering how a condor consciously 'chooses' their reproductive method at all? Do they actively dictate/control their own biology like that?

[@OppositeofHATE7]

That's what I want to know. If it's a conscious choice, that would completely change everything we thought we knew

It’s amazing that this form of reproduction wouldn’t be eliminated over time without any genetic variation. And yet inbreeding with any other species can lead to serious deformities or even death.

[@Eloraurora]

In species that can do both, it's generally a trade-off. So snails will opt more for asexual reproduction in an environment with few parasites, because the decreased genetic diversity doesn't hurt their survival, but more parasites will cause them to switch to sexual reproduction. And IIRC there's a lizard that's able to colonize new island habitats more readily because all it takes is a single female turning on the parthenogenesis switch.

Can someone please explain what the sperm does in Amazon mollies? I didn't get that part at all

9:08 🤯 Never heard of these before! Diploid male bees! I wonder what their behavior would be likenif they lived? 🤔 Could they mate and produce offspring? Fascinating!

[@rubicon24]

I like that she pronounces "processes" properly.

[@shestewa6581]

There is a type of honey bee from South Africa where a female is able to clone herself indefinitely. She also mimics the queen pheromones. So she basically takes over a nest, lays all of her eggs, and those offspring think they are also just reproductives and make clones of themselves and go to other nests and make clones of themselves. They end up overrunning the colony as no true workers are born from them, they stop working, the colony dies, and they go to another colony to do so over again. It’s fascinating.

[@FieroGT3400]

so can they actually choose to do that (like any time or place) or not? or is it more like an automatic thing that happens when a male is not present for long enough?

I feel like the way you said male drone bees mate with "the" queen, it may be mistaken for them mating with their mother. They don't do that. They fly away from their home hive to find queens of other hives to mate with. And because they are far away, they may go to a foreign hive when they get thirsty or hungry, and the host hive workers welcome the guest drone and let them in and feed them ❤🐝🐝

Scishow people, I have a question... our physical traits (appearance) is defined by our genes, but to what extent? Lets say two identical embrios are raised everything different, with one on earth, the other in space, how different can they be? Sure, dna is specific, but its not a microscopic photo awaiting enlargement! (tv idea: "the alien twins" different mothers on different planets, but twin brothers through unknown duplication of invitro eggs, who accidentally cross identities before meeting, aka: "the brother from a different mother")
