willams1 Posted February 13, 2017 Share Posted February 13, 2017 One type of natural selection is balancing selection. One scenario that can lead to balancing selection is when a heterozygote phenotype has a fitness advantage. Which of the following are reasonable predictions of balancing selection due to heterozygote advantage? Assume that after 10 generations under the balancing selection, the f(A1) = 0.2, where “A1” is one of two alleles of a given gene; “A2” is the other allele. The f(A1) will remain roughly the same over the following generations. The f(A2) will increase, while the f(A1) will decrease. The genotype, A1A2, will become fixed in the population. The f(A1A2) will increase, while the f(A1A1) and f(A2A2) will decrease. One of the two alleles will become fixed in the population. Link to comment Share on other sites More sharing options...
