... heterozygous at about 12 per cent of its loci . If these loci are truly a random sample of the roughly 10,000 loci in Drosophila , there must be about 2000 to 3000 polymorphic loci in a local population , and an average fly has 700 to ...

... heterozygous loci per individual would be 5000. The variance , however , would be quite small : 2500 ( Figure 10a ) . Thus the major- ity of the population ( 66 per cent ) would be heterozygous at between 4950 and 5050 of their loci ...
