In mosses or liverworts, separate sexes are only found in the haploid phase of the life cycle of an individual UV sex chromosomes. Even though the outcome of sex determination—whether an individual produces relatively few large ova or many small sperm—is strongly conserved, a bewildering number of underlying mechanisms can trigger development as either a male or female [3][4].

Sex-biased inheritance patterns of different genetic elements—such as sex chromosomes, organelles, or endosymbionts—create a conflict over which sex is preferred, and can drive the evolution of male- or female-biased sex ratios. Dioecy plants or gonochorism animals : individuals are either male or female throughout their life.

Retrieved 7 June Turnover of sex chromosomes can also be triggered by the degeneration of the Y and W chromosome, which commonly follows the cessation of recombination [66][67]and will result in the replacement of a low-fitness Y or W chromosome with a nondegenerate one [68].
