Fig. 8.16
Mean observed heterozygosity decline relative to decline in estimated (expected)
heterozygosity over generations for populations identical except for the distance of the 20
founders from the lower left corner. In graph A, trials were initiated with founders drawn
from a source population with 30 loci, each with 100 unique alleles of equal frequency = 0.01.
In graph B, the source populations had 10 loci, each with two alleles of equal frequency = 0.5.
The input parameters for the populations in graphs A and B were identical in every other
respect except that distance from lower left preserve corner = 0 grid units for L and l, 10 grid
units for N and n, 40 grid units for P and p, 2,560 grid units for V and v.
