The distribution of homozygosity for four alleles.
The stationary density of homozygosity is obtained for a locus with four possible alleles and symmetric mutation between them. As conjectured by F. M. Stewart (1976, Theoret. Pop. Biol. 9, 188-201) this density has spikes at 1/3 and 1/2. The density under heterozygote selection is also given.
