Heterozygosity (H) vs estimated
Effective Population Size (Neµ)
[Left] Observed Heterozygosity
(Hobs) based on protein
electrophoretic data increases with estimated population
count N over the range 0.01 ~ 0.25, as expected.
[Right] However, observed Hobs
is considerably smaller than expected from theory, as He = Neµ
+ 1). For µ =
10-7, the range Hobs =
0.056 ~ 0.185 [Y-axis] implies Ne
= 148,000 ~ 567,000 [x-axis].
