A human population in Africa living under a severe malaria selection has the following relative fitnesses (w) of homozygous genotypes in beta-hemoglobin locus: w11 = 0.75 for A1A1 w22 = 0.85 for A2A2 . Assume that w12 = 1.00 for A1A2 . Using heterozygote advantage concept, determine frequency of the mutant sickle-cell beta-hemoglobin allele (q) in this population assuming that genotype frequencies are at balance (?p = 0; balancing selection). why this population not considered a Hardy Weinberg Population

Suppose a researcher performed an experiment to determine the number of genes affecting fruit size in tomatoes. She crossed a domesticated, heirloom tomato plant with a wild tomato plant for two generations to obtain F2 individuals. In the parental lines, the domesticated tomatoes had a fruit diameter of 17 cm and the wild tomatoes had a fruit diameter of 5 cm. If fruit size is an additive genetic trait, what number of genes should we expect to contribute to this...
