Modes of selection: directional, balancing and disruptive RR Rr rr
... Disruptive selection favors fixation, like directional selection, but either allele can be the one whose fixation is favored. Again there are two principal mechanisms: -- heterozygote disadvantage (“it’s better to be pure”) -- positive frequency dependence (“the rich get richer”) All of these proces ...
