Several models were proposed to explain association between a sequence variant in SRY and 2 alternative sex phenotypes. Dumic, M.

  • Jan 29,  · This sexual dimorphism in behavior of sex chromosomes gets at the heart of the role of the Y chromosome in spermatogenesis and fertility, which is still not fully resolved. As has been comprehensively reviewed recently [ ], sex chromosomes form a unique chromatin domain in spermatocytes, the so called “sex” or “XY” body (Figure 2 Cited by: The ZW sex-determination system is found in birds, some reptiles, and some insects and other organisms. The ZW sex-determination system is reversed compared to the XY system: females have two different kinds of chromosomes (ZW), and males have two of the same kind of chromosomes (ZZ). In the chicken, this was found to be dependent on the expression of DMRT1.
