Immunogenetics 91 : — Zoologischer Anzeiger. Due to a low number of variable sites observed in DS gene, no resolute topologies were obtained for this marker data not shown. Under environmental sex determination ESDwe include sequential hermaphrodites where size plays a role in determining sex, as well as gonochorist species, where the environment can influence sex determination during development, and taxa with sequential hermaphrodites are noted separately sim.
Biomedica 27 Suppl — Polyploidy was induced in fish by Har Swarup using a cold-shock treatment of the eggs close to the time of fertilization, which produced triploid embryos that successfully matured.
Cold Spring Harbor perspectives in biology, 7 1a Biological Science 6th ed. Nature Communications. Thus, a human gamete contains 23 chromosomes, while a Drosophila gamete contains four. The chromosomes uncoil back into chromatin. Paired sex chromosomes are the X and Y homologs in males and the X and X homologs in females.

Epigenetic underpinnings of developmental sex differences in the brain. Population genetics of cultivated buckwheat, Fagopyrum esculentum Moench. However, movement of an existing sex-determining region, creating a new sex-determining chromosome from a former autosome, may sometimes directly produce a region of suppressed recombination because of the chromosome rearrangement involved see above.
