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

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

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!

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

[ThinkwellVids]

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

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

[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...

[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

[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 ?
