Evolution of neo-sex chromosomes. In the early stages of sex-chromosome differentiation, a putative PAR with recombination activity might have been formed prior to the spread of recombination suppression. Red: ancestral X region; blue: ancestral Y region; pink: neo-X region diverged from neo-Y; sky blue: neo-Y region diverged from neo-X; white: undifferentiated neo-sex chromosomal region; yellow: putative PAR. MYA: million years ago
