In mammals, male sex determination, as well as spermatogenesis, is controlled by genes on the Y chromosome. Evolutionary comparisons may be used to detect and test candidate genes for these functions, under the hypothesis that the rapid evolution of the mammalian Y chromosome causes it to contain fe
