Small founder samples make artificial selection results vulnerable to chance

Evidence

I was selecting only five individual males and ten females to found each generation. This is a small sample, and it meant that some shift in the traits of my population could have occurred by chance. If, at the end of my experiment, the males in my artificially selected population had longer horns than before, I couldn’t rule out the possibility that this was a spurious result due to chance. — Emlen, Douglas J, Animal Weapons_ The Evolution of Battle, 291
