Solving Genetics Problems

[@hap4832]

This is probably the best online tutorial I've watched. The voice is very clear. It was not so fast and not so slow. And Im actually learning. Thumbs up!

[@alleliascott8519]

Clear, concise, and a great place for my students to go and review when they get tangled up on their homework! I'll be using this for review before major exams and the End of Course test as well!

[@dashy_london3937]

I really like the way you explain! It is really clear and you show enthusiasm on the field. thx

[@JaiMeyrick1]

Really like the vid! Got an exam coming up with a genetics unit and this was really helpful :)

[@joeyhurrle5471]

I have a dream that one day this nation will rise up and expel the horrid teachers that stalk this Earth, and replace them with the Penguin Prof I have a dream that one day on the red hills of Georgia, the jocks and nerds will be able to sit down together on the internet, and fully understand complex scientific concepts thanks to the Penguin Prof I would continue...but I got an exam in 2 days! (Thank you so much for explaining 54 pgs of biology in 13 minutes)

This video blew my mind by how well it is made. You have really great pedagogy. Plus your voice is nice to listen to :) Thank you!

[@Penguinprof]

Thanks so much!!!

[@mahnoorkhan8982]

One of the brilliant educational videos and channel i've come across on youtube!

[@Penguinprof]

The female you are talking about (X+Xc) is heterozygous and will be a carrier - and that's what makes X-linked traits different. If a male gets one copy (XcY) he will be color-blind; a female needs 2 copies (XcXc) to actually BE colorblind. Hope that helps!

[@naginakhan3621]

I am feeling so good, very well explained

[@vancarylbodiola9453]

Thank you so much! this tutorial definitely enlightened me about solving probabilities in Genetics.

[@hamilton5465]

You're such a good teacher. Thanks this helped me a lot. Great job!

[@ahmedkotait]

Everything in this video was on my unit test! thank you every much!!!

[@Beatle214]

I LOVE YOU! Thank you!!!! I can't believe I didn't see this before!!!!

[@phozisaphozie1772]

I did enjoy

[@sardarmunir8758]

How to know either take homozygous allele or hetero in problems

[@ramchanderraoodela1928]

very good presentation with easy to understand the tough problems . happy to see at east now .i will pass on the message to known persons,.thanks

[@melissarainchild]

you explain things in a great way. nice and relaxed...I rewatched this one several times (and took not, of course) Thank you

[@korinamanese6042]

i have been studying this for 3 weeks and my prof only makes it complicated i am so glad i found this vid!

[@Penguinprof]

I'm so glad I could help!!

[@paolaoriada4848]

Thank u so much for this.In my school teachers arent soo good.I had a dream to be a radiologist since a kid but the teachers make me loose my dream .Here i found again a hope to be what i want.Go on please and help us .Lots of love

[@brittanycallen7974]

I wish all videos on youtube had this nice of a voice.

[@DannysFearless]

Thank you! Please make more Genetics Videos!

[@CaptainCalculus]

Hmm where I live there are signs warning that penguins cross at night, and the police will stop you if you are driving carelessly.

[@Penguinprof]

Australia or NZ??? GO LITTLE BLUE PENGUINS!!!

[@gwynethisman4620]

so is this conditional or unconditional probability?

[@hibahakim7890]

Thank you so much!

[@psyren1723]

Helped a ton!!

[@kritikakoul85]

thanks a lot for this lesson Totally changed my world of genetics:-)

[@kwnazli]

I realllyyy love you. I had an exam on thursday and im confused but your video is solved my problems thanks

[@Penguinprof]

This makes my penguin heart so happy! 🐧🐧

[@alokkumarverma1162]

Really appreciate it thanks and excited

[@Jjhperlas]

love it!! thanks for doing this video

[@ujalaabbas1861]

Thanks a lot..u hve cleared a very complex thing easily

[@ivh007]

You mean 2 dominant alleles @ 9:46. I know it doesnt make a difference to the end result. But it confused me for a bit.

[@1farhinmomtazriana25]

Thanks a lot. It was really helpful.

[@jennyyedid2]

at 9:27, how come the answer is not 9/64? Since its 2 to the 6th power, shouldn't it be out of 64? (1/4 p x 3/4 Q x 3/4 R = 9/64 pQR)

[@Penguinprof]

It's 1/4 (pp) x 1/2 (Qq) x 1/2 (RR) = 1/16 Not sure where you're seeing 2e6... Remember, if each parent is Pp for example, then for the offspring to be pp, that's a prob. of 1/2 from EACH PARENT to get it's recessive allele, so 1/2 x 1/2 = 1/4. You may be over-thinking it - I'm not sure. I hope that helps!

[@gypsypikis]

wow this was amazingly helpful!!

[@AndreaGracie]

Fantastic. Thank you!!!

[@thesilkyone2]

Awesome. Thank you

[@alliasokan8993]

need more to be explained.... nt a little bt need much!

[@essamalyk9218]

Thank you ♥️

[@Penguinprof]

You are most welcomle!

[@01aarbear]

So helpful, thank you, you're awesome!

[@Penguinprof]

+Carolina Cobian Thank you!!! And thanks for watching. :)

[@kirstenyu9258]

thank you!! super helpful

[@acsejapan]

Thank you!

[@edgargonzalez2768]

Thank you!!!

[@sruthiize]

wow, what a good video, understood perfectly

[@Vickyvictoria90]

Great vid!!!

[@marissah1413]

Very helpful!

[@loujainmhanna8404]

So helpful thanks

[@Penguinprof]

Glad it was helpful!

[@istel3283]

great video for genetics.....

[@anam3575]

I like your videos... thank you

[@margaritacalderon1475]

so helpful! thank you :)

[@margaritacalderon1475]

I have a biology test talking about only the punnet squares this video made it really easy to understand.

[@cd3dnw]

Thanks!

[@tigerhawk9712]

How is 1/6+1/6= 1/3???

[@MM-gl7ll]

1/6 + 1/6 = 2/6 = 1/3

[@G5Nvm]

boy wtf

[@sarashaikh1416]

wow this made a lot more sense!

[@MsPilpilon]

Great video very useful Tnx!

[@snehadas5627]

Thanks a lot.. helped me a great deal :) :D Keep going ! :)

[@Penguinprof]

+Sneha Das You are so welcome! I plan to!!! :)

[@ingothitrust5248]

Why does the probability scheme fall apart when you have 2 Heterozygous parents to find the probability of Heterzygous offspring? Obviously through the Punnett square, it's obviously 50% of 1/2 but when you use probability, it comes out to 1/4 or 25% Am I missing something here?????

[@Penguinprof]

Remember that Hh is equivalent to hH, so you need to add 1/4 + 1/4 to get 1/2.

[@axe4770]

I LOVE YOUUUU

[@truax1101023]

That albino kid will haunt my dreams

[@PastorKemp]

So, if you have a homozygous dominant parent with AA and heterzygous dominant parent with Aa; What is probability of getting offspring of aa? Would it be 0?

[@Penguinprof]

Yes - it would be 0. There is no way to have an 'aa' offspring, since it would need one recessive allele from each parent and the AA parent does not have one to donate.

[@DarkPrinceNH5570]

Yes I have a bump on the side of my left hand like its a birthmark. Its not, I use to have a 6th finger. Im polydactyly. Its rare to see I guess amongst people on earth. Yes others have it but the chances of getting its rare. I was inherited this through my blood.

[@bettyromandia6567]

*Can anyone recommend research paper writing service?*

[@jeanahukle4148]

*essay.4v20.all-about.in* Finance paper was a total disaster for me before I found this website. I didn't know where to start, what to write, but they showed me everything and now I am sure that with their help I can cope with any possible assignment.

[@ravitejaraviredmills]

is this still in need?

[@somethingsafoot]

write ur own essays idiot

[@jeanclaude6284]

Uzaam Syed lolz!!! Super Savage

[@psptubegray]

can you pls do this with out the square.... In horses, B=black coat, b=brown coat, T=trotter, and t=pacer. A black pacer mated to a brown trotter produces a black trotter offspring. Give all possible genotypes for this offspring.

[@DarkPrinceNH5570]

The 6th finger on my left hand was cut off at birth. Other famous people and ROYAL FAMILY MEMBERS are polydactyly too. Look it up.

[@kislikalkulator]

11:18 i need this part for presentation. (Shortcut)

[@jonathanramirez4830]

Thanks!! I like penguins too!

[@makeupartistinbangaloredee6349]

Good video

[@Penguinprof]

Thanks!!

[@reneric1]

why isnt the probability of having a color blind child (in your example) 1 in 4? there are two squares with Xc

[@divyanarayan3723]

Thank u

[@peterojugo7542]

you rock

[@bhagya2624]

this really helped me, thank you

[@Penguinprof]

You are most welcome!!!

[@mailynruth5704]

The comments are all years ago, y'all still alive out there?...

[@Penguinprof]

Yup, still here!!!

[@PoisonousPotato69]

God damn this is easy after this video

[@DarkPrinceNH5570]

So if Im polydactyly does that mean I could have more or less chromosomes? If anything with the chromosomes it should mean I have more chromosomes. I bet I dont, I bet its normal. It could be something else that caused that deformity at birth. I dont want to say anything just yet because I dont know enough about biology but yeah I been to hell and back. Its messed up and I was always curious about this.

[@liganjinxeseverything3174]

My word... genetics is not so very different from linear algebra and matrices. Anyway, pretty good presentation.

[@RebelLife05]

12:53, why is the mother not X+ X+..since she is carrying the color blindness, 13:19, why is the male child chosen as the answer,

[@dustinwebber8904]

the mother is stated as a carrier, this means that she has that recessive trait but doesn't express it...therefore it is correct the way it was shown

[@mistymcclure1955]

Can A+ mother and O + father. Can they make an AB+ baby

[@Penguinprof]

Nope. That B antigen has to come from someone!!

[@ameen6796]

Maths is great !

[@spiderman_2579]

Thanks mam

[@Penguinprof]

You are welcome!

[@okaypinkplays9893]

@5:47 i see what you did there

[@Penguinprof]

+rose'n'games That was the required intersection for my dating criteria - Fabio was the result. :)

[@learnnetneetintamillanguag5049]

super thanku

[@recentnews7151]

Nice

[@DarkPrinceNH5570]

I dont know enough about biology but it hasnt been proven no matter what. This is weird because they put stuff in media saying this all the time as if I reminded them of someone in the past recorded in a history book or journal that no one knew about. So who did I turn out like?

[@yogeshgupta4667]

a colour blind man marries a woman with normal sight who has no history of colour blindness in her family. What is the probability of their grandson being colour blind??

[@bonnielee7559]

I did NOT get this

[@mhdsbz807]

ausome....

[@okaypinkplays9893]

@1:40 dat face tho...

[@TheArgarc]

Females have to carry two copies of the color-blind allele to be color blind. Males only need and can only accept one sex linked allele for the phenotypic trait to show.

[@rahulsonaniya7636]

if son have blood group A and AB and daughter have blood group A and B find the blood group of parents

[@belieberbeth123]

autsomeee👏🏽😂

[@okaypinkplays9893]

penguin.....? O_o

[@ben456tone]

Why are you talking about mathematics instead of genetics that too in a sloppy way

[@PinkiSingh-tb8mo]

nic1!

[@okaypinkplays9893]

+Pinki Singh ikr???

[@PinkiSingh-tb8mo]

+rose'n'games what??

[@okaypinkplays9893]

something

[@TheFutureGhostHunter]

more lke your showing off what you know verses teaching... sorry but it is good ideas and share... but teach more
