For the first, researchers in Uppsala have mapped the. 12 Feb Sex differences in life span: Females homozygous for the X chromosome do not suffer the shorter life span predicted by the unguarded X hypothesis . In the heterogametic sex, however, most X(Z)-linked loci do not have a homologous copy on the Y(W) chromosome, which may cause this sex to suffer. 10 nov Abstract. Sexual reproduction is found in most eukaryotes and has in the majority of animal species led to the evolution of separate sexes. In contrast, only % of all angiospersms are dioecious with female and male flowers on separate individuals. Interestingly, dioecy has evolved hundreds of times.

Survival of genes during W chromosome degeneration has been highly non-random and expression data suggest that this can be.
