XY difference cannot be attributed to the direct effects of Sry. Sessions SK Cytogenetics and evolution in salamanders. These features were independent of the number of genes averaged to smooth the curve. External link. For each tissue, all genes showing expression from the Z chromosome or from autosomes were grouped into bins according to M:F ratio.

Unless it is something very critical where these chromosomes might deviate, the autosomes will follow a usual trail or map in the normal circumstances. Other 22 are autosomes. However, these defective alleles are very rare in the human population. An Introduction to Genetic Analysis.

As discussed above, the current theory of sexual differentiation suggests that the X and Y chromosomes harbor numerous genes that are the primary factors causing sexual differentiation, because these factors are inherently unequally represented in XX vs. The model does not solve whether these sex chromosome effects are caused by the number of X chromosomes 1 versus 2 or the presence of the Y chromosome.

Melamed, E.

The role of epigenetics in sexual differentiation The recent explosion in study of epigenetics has several important effects on the study of sex differences. The loss of recombination between the proto-Z and proto-W at this location would have brought the newly hemizygous segment of the Z chromosome under sex-specific selection pressure to compensate Z gene dose.
