Synteny: Inferring Ancestral Genomes. These latter functions are controlled by 5a-dihydrotestosterone Figure Often, it is these very exceptions or modifications of expected patterns in mitosis and meiosis that enrich our understanding of how the transfer of chromosomes is regulated from one generation to the next.

One daughter cell thus ends up with more chromosomes in its nucleus than the other. These cords are split into clusters, with each cluster surrounding a germ cell Figure The developing gonads The gonads embody a unique embryological situation.
In particular, Sutton pointed out that the independence of each chromosome during meiosis means that there are 2 n possible combinations of chromosomes in gametes, with "n" being the number of chromosomes per gamete. However, in those tissues where the translocated X chromosome is not inactivated, the SRY gene will be on Berkovitz et al.
These epithelial layers form the sex cords.
