antagonistic pleiotropy hypothesis

For these experiment assume allele A = red, allele a = white . There are three flower colors (phenotypes and genotypes) for this species where AA=red, Aa = pink, aa = white. • A population of Four O-Clocks is in Hardy-Weinberg equilibrium and no evolutionary forces are acting on the population. Bees are introduced into the population. Individual bees only visit a single color of flower so that red flowers only mate with red flowers, pink with pink, and white with white. Assume you start out with a population where the frequency of the A allele is 0.2 and the population is initially in Hardy Weinberg equilibrium. What would the frequency of the Aa genotype be in the the next generation where positive assortative mating is 100% (i.e. there is no random mating)?

Which type of selection best describes the shift in peppered moth from the light form to the dark form following the industrial revolution? Directional Stabilizing Disruptive 58

According to Hamilton's Rule, in which scenario is selection for cooperative breeding expected to be the strongest? but lose the chance to have Helpers raise and increase the survival and reproduction of of their own offspring. O 100 additional 2nd cousins twice removed to whom they are 0.00781 (0.781%) genetically related; 2 of their own offspring. 60 additional 1st cousins once-removed to whom they are 0.0625 (6.25%) genetically related; 1 of their own offspring. O 50 additional grandnieces/nephews to whom they are 0.125 (12.5%) genetically related; 2 of their own offspring. None of the three scenarios are likely to result in the evolution of cooperative breeding according to Hamilton's Rule.

Which of the following mechanism(s) will lead to a decrease in heterozygosity? Select all that apply. Multiple correct  - genetic drift - migration - positive assortative mating - mutation - negative assortative mating   I tried genetic drift, negative assortative mating and mutation - that was incorrect I also tried genetic drift and negative assortative mating - that was also incorrect Lastly, I tried positive assotative mating, genetic drift and migration - that was also incorrect

Using the informationgiven and scenario 1, tell whether the BB, BR, and RR phenotype, will increase, decrease, or do both increase or decrease or it will stay the same.

Why does the response to selection often level off after many generations of selection?
