Zygote differentiating into somatic and germ cells | MCAT | Khan Academy

Learn how a zygote, the single cell produced by fertilization, divides by mitosis to produce all the tissues of the human body (including germ cells, which can undergo meiosis to make sperm and eggs). Created by Sal Khan.

4:00 - 4:57 hahahahahaha. his commentary to drawing is hilarious. i love how open this guy is

[@nathuwjohn]

The self portrait, drawing, had me cracking up over here! =D
Always EXCELLENT info!

[@Pow3llMorgan]

I was more amused than I should over hearing Sal saying 'The gonads are the testies. The testies.'
As always, though, very interesting and informative.

[@prateekchauhan6376]

thanks for clearing my doubt.. i thought both mitosis and meiosis took place in zygote... but now i know that only mitosis take place in zygote and meiosis takes place in gonads which are a consequence of mitosis

[@baijanmarak3702]

Thanks

[@Kymv8382]

Nice broad shoulders, that's nice. lmao

[@hassanabdul-kareem1882]

Thank you. that was so informative.

[@unclesmrgol]

Is not the zygote a human being at the earliest developmental stage possible? If not, when are the requisite number of mitoses necessary to define the human being?

[@Bill_G]

thought the same thing

[@user-mk8bl1uc8x]

Amazing video! Thankyou! Helped me with understanding somatic and gonadal mosaicism.

[@buttercup4440]

I love the way you break down the process of mitosis and meiosis

[@michyyy102]

LOL the drawing was hilarious! and all the comments you made added to that.

[@medicalstudent201]

What would Have I done without you???? Thanks... Wish all the good luck for you...

[@albertro88]

Do u have any video on Prophase, Metaphase, Anaphase, Telephase and cytophase?

[@tonydigiovannisingerentert5773]

If the cells are IDENTICAL what makes them differentiate into DIFFERENT cells?

[@tejasvisakhamuri1380]

“Some of these cell are going to differentiate into me” @3:14 - so cute

[@anusha3033]

Your general idea drawing of human being is much better than my drawing which takes more than a hour to make its way to the final draft 😂

[@calskankz2267]

Turkish subtitle please.

[@N3omega]

Only koreans do this, chinese use chickens
