Mitosis vs Meiosis (updated)

This updated video compares and contrasts the processes of meiosis and mitosis. This video is shorter (less rambling on my part), widescreen maximized for cell phone use, and cleaner animations.

[@arino274]

I find it amazing that what my professor could not accomplish/teach in an hour and 30 minutes, you were able to explain clearly in less than 10 minutes! Thank you so much :) I hope you have a great day

[@mariaorsic9763]

BY FAR THE BEST, BEST, BEST, EXPLANATION AND VISUAL I HAVE EVER, EVER, HEARD on contrasting meiosis with mitosis. NO ONE EVER ANNOTATES WHICH is the mother AND the father. I have spent 5 months trying to get this straight. I have looked at no less than 100 videos including Shomu, Professor Dave, and the Amoeba Sisters. NO ONE DEFINES THE MOTHER FATHER PIECE( black and red) AND so I have never gotten the big picture.

Thank you for your kind words...stay persistent... don't give up trying... best wishes to you.

[@cariboux2]

Thank you very much for this excellent video. It's probably the clearest explanation of Meiosis (vs. Mitosis) I have yet seen. Your students are very fortunate - from an older life-long learner.

Really awesome I was taught mitosis and meiosis 4 times and this is the first time I understand it.thank you so much.

[@taylorstohl1281]

Thank you so much for the video. I appreciate the visuals and the slow pace more than you know!! :)

this is the best video, thank you friggin much. jesus all of the other ones suck so much. you need more views!

I love your videos. Excellent at describing the steps.

Im glad i learned it clearer. Thanks a lot 😁

[@poojachaudhari1331]

amazing amazing video ! thank you

[@ozzythelovemachine]

One of the best videos i've seen. I shared it with all my friends. For future updates, could you mentioned earlier on the video when we have Chromatids vs Chromatins? Do we get chromatids as soon as Interphase is over or when we are in Anaphase as you first mentioned them (5:11)?

[@ME-xh5zq]

ozzythelovemachine When prophase begins the chromatin changes to condensed chromosomes. Each strand in these chromosomes are chromatids.

[@ME-xh5zq]

Super underrated!!! The best biology channel I've ever seen.

[@luenedragos]

The numbering really confuses me, so if I just look on the left side at the Mitosis: At 1:13 the chromatin is like this (1 Paternal) (2 Maternal) (3 Paternal) (4 Maternal) At 1:44 the chromatin duplicates (1&1 Paternal) (2&2 Maternal) (3&3 Paternal) (4&4 Maternal) At 2:27 the chromosomes are now (1X Paternal) which used to be (1&1 Paternal), but (1X Maternal) used to be (2&2 Maternal)? and (2X Paternal) used to be (3&3 Paternal)? and (2X Maternal) used to be (4&4 Maternal)?

[@leemoore5212]

I agree. The only criticism that I have of this excellent video is that it's not possible to keep track of which chromasome / chromatid is which. ie red and black distinguish mother and father inherited chromosomes, (and the mixed up crossed over ones) but nothing (except occasional but not persistent labelling) distinguishes chromo number 1s from chromo number 2s. The only way I can think of to do this, which is visually easy, would be to make the two illustrative chromosomes / chromatids obviously different in length. So the number 1s might be drawn to be 150% of the length of the number 2s. Then you could keep track of which chromasome/chromasid was which, as well as which bits of DNA were maternal or paternal, as well as the life history of each chromatid strand as it goes through the dance.

Any chance you could add official English captions for accessibility, please? Thank you!

[@shinexungiignatius]

thank you sir

[@LauraLM]

Great video thank you!! Just I think there's a mistake - at the end of Telophase in Mitosis if you start with 1 and 2 (2 of each) you end with 1 and 2 (2 of each... after S phase) ... not 1, 2, 3, 4.

[@nikirahimi2797]

each diploid cell in mitosis ends up making 2 diploid cells. In meiosis, each diploid cell ends up making 4 haploid cells (sex cells)

[@surangafernando3450]

Can you make videos on monohybrid and dihybrid inheritance and autosomal linkage please?

[@nidakhan2025]

why are there 2 chromatids from mother and father each? are we a taking into account 2 chromosomes?

[@BeverlyBiology]

I don't understand your 2nd question. As for your first question, the diploid number for this animated cell is 4, therefore 2 strands of chromatin from each parent. In humans, the diploid number is 46, so we would have 23 strands of chromatin from each parent.

[@ezzovonachalm7534]

Is this to say that cross over does not occur in humans - who are necessarily diploid with 46 chromosomes ??? So there were no genetic mingling between paternal and maternal chromosomes ? Am I the sole dude having heritated some phenotypic traits from my father and other from my mother ?

[@stephanieramirez428]

Great Video ..It was helpful and he Question in the end.But for those of us that are only able to see you video can u post the answer to see if we are right and understood it

[@snewman6]

Helpful video! I think the only thing you failed to mention was that the cells are haploid at the end of Meiosis I.

[@BeverlyBiology]

well... I tried.. ha ha... thanks for watching

[@giselgutierrez9476]

why are cells haploid at the end of meiosis 1??

[@snewman6]

Because there is half the original chromosome number...

[@aricman100]

I have to disagree with you. I believe that there are two Diploid cells at the end of Meiosis 1. Let's look at some definitions: The definition of a Diploid (somatic cells) - Each cell has 2 copies of each chromosome. The definition of Haploid cells (sex cells) - Each cell has 1 copy of each chromosome. At the end of Meiosis 1, when the cell is split into 2 cells, there are still sister chromatids in each cell. Remember, that in Anaphase 1 of Meiosis 1, the homologous pairs were pulled apart (the tetrads were pulled apart), not the sister chromatids. Each sister chromatid consists of two chromosomes and we will still have sister chromatids in each cell at the end of Meiosis 1. Since there are still 2 copies of each chromosome in a cell, that would make it a Diploid cell. Once those cells are pulled apart (in Anaphase 2, Meiosis 2) and their sister chromatids are pulled apart, each cell will now have only 1 copy of each chromosome, resulting in 4 Haploid cells.

[@ME-xh5zq]

Ari M 'each sister chromatid consists of two chromosomes' This is where you had made the mistake. 2 sister chromatids makes 1 chromosome. So at the end of meiosis 1 there are 23 chromosomes in each of he 2 daughter cells (46 chromatids in each).

[@joyfadele3104]

Thx

[@sakshiredkar4234]

Sir please make me clear that as mitosis only And only occurs in Somatic cells......then under mitosis how u r denoting as Maternal and paternal!???.....there is no fusion of gamates in mitosis...
