rocketpig,
I dont see why an interesting character would disappear if it improves the selective capacity of the owner whatever the population is large or small..
Of course, in a large group, the % of individu having the new allele will increase slowly compared to smaller group but it is not a problem to my eyes.
The only thing I can imagine is that the probability to have homozygote individu will be increased in smaller group allowing maybe a better selection of these individu.
Time to Work !
