Cell 43 : — However, because sex determination changes so rapidly in many clades, we can catch these transitions in action to test theoretical predictions in a direct, experimental way.

The nature and evolution of sex-determining genes and pathways Some taxa have master-switch sex-determining genes that are highly conserved, such as the Sry gene in nearly all mammals [77].

  • A sex chromosome , also referred to as an allosome , heterotypical chromosome , or heterochromosome , [1] [2] or idiochromosome [3] is a chromosome that differs from an ordinary autosome in form, size, and behavior.

So as you may recall, if you are XX, you are female. Male heterogamety: type of genotypic sex determination in which males are heterozygous for the sex-determining locus termed X and Y, as seen in therian mammals and Drosophila. Thus, the evolution of sex-determining pathways, at least in animals, appears to occur by the recruitment of new master-switches controlling sexual fate, while the downstream developmental pathways that regulate gonadal differentiation are retained [10] , [81] , [] , although the function of some of these downstream elements appears to diverge among lineages [].
