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. (-5[1])Along with fitness, this phenomenon decreases in a population (-5[1])during inbreeding depression. (-5[1])In humans with the cystic (10[1])fibrosis gene, this phenomenon is hypothesized to result in cholera resistance (-5[1])in its namesake advantage. 2pq (10[2])gives the proportion of organisms (10[1])that display this phenomenon during Hardy–Weinberg equilibrium. Incomplete dominance causes camelias displaying this phenomenon to appear pink rather than red or white. For (-5[1])10 points, organisms have two different alleles for a given trait in what phenomenon contrasted with homozygosity? ■END■ (10[4])
