you go at such a perfect speed at normal that when you speed up 2x everything runs smoothly and you can still understand everything. can't thank you enough for these

For those wondering, @ 4:52 the screen is clear and you are able to pause and read the whole thing or take screen shots for notes.

Can we still call it chromatid if it is in Anaphase II? Because technically they are genetically different?

thank you very much for your videos. I am confused though. How can you say that Meiosis 1 ends with 2 haploid cells? it does not make sense because you also divide the number of chromosome in the end of meiosis 2. would that mean that the 4 haploid cells would have a quater of the original number of chromosome.

I think you can picture it that way : At the end of M1 you have two haploid cells. Each one of them has 2 sister chromatids - one of them is practically the original chromosome from the homologous pair ( the one you inherited from your mom, for example) and the other one is the one that went through crossing-over so you can think of it as a modified copy if its sister chromaitd. So you end M1 with 2 chromosomes, but 4 chromatids. Does that make sense? Okay, when you go through M2 the sister chromatids divide and each form an individual haploid cell. It is haploid because it contains only one chromosome. So at the end of M2 you have 4 haploid cells and a total of 4 chromosomes. I hope that it helped clear things a bit.

End of Meiosis 1 produces 2 haploid cells (23 chromosome) containing sister chromatids which then produces 4 haploid cells without having any sister chromatids at the end of Meiosis 2.

The four haploid cells that produced is from only one homologous pair , and humans have 23 pairs of chromosomes so sperm and ovum ends up with which chromosome and if it ends like this how we inherited these combinations of genes from only one homologous chromosome ? what about other chromosomes where they end up and how we inherited? Thank you so much for your videos. You are awesome man.

why the centrioles duplicate . why not a single centriole forms spindal fibers

i have a question........ you said that interphase happens first before meiosis and mitosis ..... so is it going to happen again in meiosis 2 ? and if it's not ! then how did the centrioles duplicate??????
@zekky1000
@zekky1000 8 жыл бұрын
I know DNA replication doesn't happen (Which you probably figured out too) centriols are always 2 and hold in the centrosome, I think in meiosis 1 the centrosomes duplicate to hold to centriols but don't take my word on it, it just a thought lol

Yes interphase occurs after Meiosis 1 too. Interphase means cell growth phase. Cell doesn't divide until it grow enough size (see cell cycle process of AK lectures)
