Re: Minimum number of males in a breeding population

Or if you want to see it in graphical form, see:

what I made.

A graph of effective population size for absolute populaiton size
N=10000 and varying Nos of males. The second half of the graph for
N>500 males not shown is a mirror image of this side.

All you have to do now is decide what the minimum allowable effective
population size is and take a reading off the graph there. When there
are few males, an extra male increases Ne quite a bit, but the more
males there are the less this effect -- up to 5000 of course, after
which there are too few females and so Ne decreases again.

However, the graph fails to take into account other factors that affect
Ne such as, non-overlapping age structured populations and Unequal
contributions to the next generation.
