What is a formula for calculating the effect of unequal

numbers of males and females (non-random breeding)on Ne?

Ne = 4 MF M = # of breeding males

M + F F = # of breeding females

Population A Population B

M = 50 M = 10

F = 50 F = 90

N = 100

Ne = 4 x 50 x 50 = 4 x 10 x 90

50 + 50 10 + 90

= 100 = 36
