AbstractMany diverse systems for sex determination have evolved in
plants and animals. One involves physically distinct (heteromorphic)
sex chromosomes (X and Y, or Z and W) that are
homozygous in one sex (usually female) and heterozygous in the
other (usually male). Sex chromosome evolution is thought to
involve suppression of recombination around the sex determination
genes, rendering permanently heterozygous a chromosomal
region that may then accumulate deleterious recessive
mutations by Muller
