GENE ACCUMULATION. “The Y chromosome is thus expected to accumulate genes beneficial for male functions, confining them to males, and male attractiveness genes in guppies are indeed often partially Y-linked. Once such genes have accumulated, there is a selective advantage to suppressing crossing over between them and the sex-determining regions of the proto-sex chromosomes.”
