The following question refers to the graph of mutation-selection balance below. Which of the following statements correctly explains why the curve for selection increases as q increases? 1. Selection is always a strong evolutionary force II. As the frequency of q increases, the frequency of aa homozygote individuals increases III. When the frequency of q is low, most recessive alleles are found in heterozygotes, which do not have the low fitness genotype. Change of q, Aq mutation selection Frequency of a, q
