Two males are fighting for territory that will increase the probability of mating success. Which term best describes this activity? O Intrasexual selection O Intersexual selection O Artificial selection O Mutation

The MN blood group is of interest to population geneticists because (a) people with genotype MN cannot receive blood transfusions from either MM or NN people (b) the MM, MN, and NN genotype frequencies can be observed directly and compared with calculated expected frequencies (c) the M allele is dominant to the N allele (d) people with the MN genotype exhibit frequency-dependent selection (e) people with the MN genotype exhibit heterozygote advantage

What type of selection is this?

If female rabbits prefer longer eared males, but shorter eared males are less likely to acquire life- threatening infections of the ear, what overall pattern of selection should be observed when these processes happen together? disruptive directional stabilizing O balancing

Stabilizing selection happens when O Large and small values of a trait are selected against Medium values of a trait are selected against Only large OR small values of a trait are selected against

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 statements about inter- and intra-sexual selection is FALSE? O Males are typically the sex experiencing intrasexual selection because they are generally limited by access to mates, whereas females are generally limited by access to resources. Intersexual selection can explain the occurrence of extravagant display traits in males such as the ornate coloration in guppies. Males competing against each other to aquire the best nuptual gift is an example of intrasexual selection. O Either intersexual or intrasexual selection may occur within a population, but not both.

Selection operates on a trait with a normal distribution. If after selection, the mean in the trait has not changed, but the frequency In the trait has increased at the extremes, of: O disruptive (or diversifying) selection O directional selection O stabilizing selection O frequency-dependent selection
