Genes on the marsupial Y chromosome
The XX female/XY male sex chromosome system of therian mammals evolved from a homologous pair of autosomes following evolution of a testis-determining factor on the Y chromosome. Over time, male-advantage alleles accumulated around the sex-determining locus leading to suppression of recombination between the X and Y to preserve the male specificity of this region. In the absence of recombination, the Y chromosome serially degraded, resulting in the dimorphic sex chromosomes seen in extant...[Show more]
