Hi SDN family,
I am completely confused about one aspect of meiosis.
Gametes are haploid cells having one chromosome of the possible 23 chromosomes in humans. But how the heck do gametes start prophase I with sister chromatids of 46 chromosomes. From my understanding, gametes have 23 chromosomes, a mix from both parents. They do not have 46 chromosomes (one chromosome from EACH parent), like that in somatic cells. If this is the case, how does interphase add a whole set of 23 chromosomes to the gamete so that it now has two chromosomes sets (maternal and paternal) which will be replicated to start prophase I with 96 chromosomes?
I am sorry, my question is probably confusing. Hoping someone can understand it.
Thank you
