Observed number of each genotype ■ ● A1A2 =20 A2A2 = 40 ● A₁A1=36 A1A2=28 A₂A2=36 Note that raw numbers are given. The question is whether observed frequencies = expected frequencies. You must first compute the genotype frequencies.

QUESTION 7 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 Kk and 160 kk. How many larvae would survive to adulthood? O 170 O 417 583 750 830 (Following up on Question 7.) What would be the KK genotype frequency at the adult stage? O 0.090 O 0.270 O 0.325 O 0.360 O 0.529 QUESTION 8

The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes? * nd 2 school The proportion of DDT-resistant mosquitoes in a population remains constant due to the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is introduced to a rainforest. Over the next year, the finches showa death rate of…
