The proximate factors causing sex differences in physiology and disease are primary acute activational effects of gonadal hormones, organizational long-lasting effects of gonadal hormones, and sex chromosome effects not mediated by gonadal hormones. The X chromosome is a hot spot for sexually antagonistic fitness variation.

First, it could be the consequence of a heteropopulation lacking the appropriate suppressor for segregation distorters. When a specific cytosine is found to be methylated a few percent more often in one sex than the other, it is not clear how large a functional impact would be expected on gene function.

However, increased sexual selection and conflict can also affect Y chromosome evolution.

In many cases, these differences are caused by the long-lasting or permanent organizational effects of gonadal hormones Arnold and Gorski, Intralocus sexual conflict resolved through gene duplication. The likelihood that a sex-determining gene will be proximate to a locus with sexually antagonistic alleles is in many ways defined by the proportion of loci in the genome with sexually antagonistic effects.
