Oogenesis: Meiosis in Females, Part 2 of 2, from Thinkwell's Video Biology Course

[MrHappytaffy]

home school at its best. thanks alot of the perfect explanation

[yadahmean]

love resorting to youtube videos rather than reading the text book :) visual learner. lol thanks for uploading!!

[adarshadublintennis1]

Struggling to revise, no longer struggling now!!! Absolutely brilliant sir!!!

[IMHALUX1]

wow sir! you have a special touch to teach!! thank you!

[alaazahra]

I would think evolution decided not to give us 4 gametes because it would naturally select against that, being that the mother is most likely to die if she had 4 babys growing in her body at times where food was scarce ? or maybe it would kill her if she had for example 4 cells to develop into twins or triplets ! that would be fatal don't you think ?

[BillieBaby143]

@alaazahra I don't think it would be that fetal. Twins are naturally occurring phenomenons. Women give birth to twins everyday.

[lynahar]

thanks . this video helps me a lot ! yay :D

[BillieBaby143]

Can you explain how meiosis occurs after fertilization? It's hard for me to grasp that concept for some reason.

[alaazahra]

@BillieBaby143 Meiosis does not occur after fertilization, mitosis however does... to replicate the cell and grow into a baby.... when the baby gets to maturation age (around 12) he will undergo meiosis

[BillieBaby143]

@alaazahra Meiosis in females does not complete till it meets the sperm. Technically it's not an ovum until then, it is considered a secondary oocyte. When the secondary oocyte is released from the ovary and meets sperm, meiosis II proceeds, AFTER fertilization... Crazy, I know...

thank you teacher..greetings from asia

[AliUnited9112]

i have a question. he said they make one OOcyte II in a month. while they make about 500 but only one or two survive.

[cookiesaywhat]

i was sitting up here reading my hard as hell textbook and freaking out cause i didnt get a thing..so i thot what the heck,,,ill check out some thing on youtube..and i came across you

best decision i ever made! thnx man i owe you one

[jtamayo6]

isn't the zyGOTE 2N after fertilization?



[pickaname444]

[preppycuttie3]

This is amazing!!! i am studying for the mcat and this is BEYOND helpful!! thank you so much proffessor wolfe!! :) i have an excellent understanding of what i am learning becaues of u! I wish all my teachers could teach like you!!! :D

[digitalmadheads]

"sadly being the mother" not the best thing to say =/ but helpful - make the diagrams in the books come to life and easier to follow through.

[humanbiolaccount]

Thank you so much for uploading this! I had so much trouble trying to understand this in class but I understand it now :)

[ThinkwellVids]

@humanbiolaccount Professor Wolfe is great at explaining things. Glad the video was so helpful!

[xSPF20x]

ohh please use an erasable board or something.. my heart dies with every paper you rip! Otherwise it's extremely helpful. Very good explanations in simple understandable language

[nehajohar]

can't believe I understood the whole process in 5 min :) prefer this then attending early morning lectures:) really like the way he teaches:) 5 stars to him:)

[doflegend291]

tyvm very helpful

[luvluvluv741]

OMG THIS MAN IS AMAZING!!! my hands are itching to buy the lectures

[ThinkwellVids]

@luvluvluv741 I've been watching the lectures for quite a while and Professor Wolfe is really great. He has a fun sense of humor and obviously enjoys teaching. Glad you enjoyed the video!

[jcs3733]

[unopepito06]

So what's contained in the polar body?! Nothing?

[ThinkwellVids]

@unopepito06 No they contain cytoplasm but it's a very small amount.
