Extract

A classical question in population genetics is ‘In a species in which there is obligate outcrossing is there an increased amount of heterozygosity?’. This somewhat vague question can have two different meanings: (1) Is the number of alleles maintained at a locus greater? and (2) If there are two alleles at a particular locus is the number of heterozygotes formed greater? It is the last question which is discussed here.
