You are working on an undergraduate project, studying an insect species. A recent study showed that the pigmentation pattern used for camouflage is made by an enzyme K. However, it has been shown that, when compared to the Kk individuals, the KK homozygotes would have a higher chance of dying from pigment overdose before growing up, while the kk individuals can easily fall to predation before becoming adults. In fact, when compared to the Kk individuals, the estimated selection coefficients for KK and kk are 0.25 and 0.5, respectively. You are interested in what would happen to these alleles. At present, you have conducted a population survey and have 1000 larvae in your collection. Among them, 360 are KK, 480 Kkand 160 kk. 1)How many larvae would survive to adulthood a) 170 b) 414 c)583 d)750 e)830 2)Following up the previous question, what would be the KK genotype frequency at the adult? a) 0.090 b) 0.270 c) 0.325 d) 0.360 e) 0.529 3)Following up on the previous question, what is the Kk genotype frequency for the next generation larvae? a) 0.141 b) 0.236 c) 0.282 d) 0.473 e) 0.48
