Due to this phenomenon, sheep with either a mutated BMP15 or GDF9 gene were found to display increased fecundity. Organisms that display this phenomenon are selected against during disruptive selection. Along with fitness, this phenomenon decreases in a population during inbreeding depression. In humans with the cystic fibrosis gene, this phenomenon is hypothesized to result in cholera resistance in its namesake advantage. 2pq gives the proportion of organisms that display this phenomenon during Hardy–Weinberg equilibrium. Incomplete dominance causes camelias displaying this phenomenon to appear pink rather than red or white. For 10 points, organisms have two different alleles for a given trait in what phenomenon contrasted with homozygosity? ■END■
