He explained Anaphase I when he discussed Independent Assortment. It was easy to miss. It was a short transition from Metaphase I to Anaphase I to Telephase I. I hope this helps.
when the DNA doubles at the start it is seen as having twice the amount of genetic information. however, when the first set of haploid cells have sister chromatids , just because they are the same it isnt counted as diploid. well it was counted as tetraploid during DNA replication!?
Before the meiosis 1 dna duplication occurred in s phase and in meiosis 1 chromosome number is half but in meiosis 2 dna duplication does not occur why the chromosome number remains same .
This is really one of the most helpful videos of this process so thank you, but i have a question that i havent been able to find the answer to. Why form 23 chromosomes? what dictates this number to be 23 or 46 in each cell?
One of my teachers has given us a study guide and you covered everything but a cleavage furrow and cell plate. So i was wondering if you could clear that up a little. And i have a question. What is the difference between independence assortment and crossing over i don't understand?
Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes. Source: Wikipedia
Very helpful. Thank you so very much for educating folks in an easy to understand format. Your videos are very much appreciated.

this was so helpful! THANK YOU!!
this is quit a good 1........understood everything........!!!!!!
My god, this answers so many questions.. Thank you
It sounds like your whispering.
good video thank u sir
Thank you....helped in my.. gynecologic subject

there is nothing about forming zygote dont be confused.just focus gametes.also youll got the point human repuraduction system that zygot stuff

does Anaphase 1 end up with daughter cells with haploid or diploid number of chromosomes ??
Didnt you miss the Anaphase I?
I am a little confused. Is meiosis the process by which the gametes are formed or the process by which the 2 gametes come together and form a zygote?
Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes. When two gametes (an egg and a sperm) fuse, the resulting zygote is once again diploid, with the mother and father each contributing 23 chromosomes.

Why do you refer Meiosis Reduction division?
Cuz it reduces the chromosomal numbers into half
