Chapter 16.3, Problem 2TC
If we studied a population of bighorn sheep and were able to identify the father and mother of each lamb born, would you predict that the difference in number of offspring between the most reproductively successful adult and the least successful adult would be greater for males or for females?

If self-fertilization causes lower fitness than cross-fertilization, under what environmental conditions would self-fertilization be the superior strategy?
Given the results of our calculations of inclusive fitness for male pied kingfishers (Ceryle rudis) (see Table 13.1), isn’t it maladaptive to be a delayer? Why aren’t there any completely sterile helper male pied kingfishers?

You are examining a gamete pool of recently collected salmon that will be used by a fish hatchery program. You were looking for evidence of linkage between two loci (A and B), but before you can do that you need to calculate allele frequencies and haplotype frequencies. You examine a total of 200 sperm and 200 eggs and of those you observe 36 gametes have the AB haplotype, 264 are Ab, 12 are aB, and 88 are ab. Which of the following best describes the allele frequencies of the gamete pool?
a.
fA=0.25 fB=0.88
b.
fA=0.69 fB=0.31
c.
fA=0.75 fB=0.12
d.
fA=0.375 fB=0.125

In this population, one gene (G) controls spot color in giraffes, which shows incomplete dominance. Individuals with white spots are homozygous gg, individuals with brown spots are homozygous GG, and heterozygotes have orange spots (Gg). You observe 25 white-spotted giraffes, 15 orange-spotted giraffes, and 22 brown-spotted giraffes. Calculate the observed allele frequencies, using p for the frequency of allele G, and the expected number of giraffes of each phenotype assuming Hardy-Weinberg Equilibrium (do not do the entire chi-square calculation!). For frequencies, report four positions after the decimal. For expected numbers, report two positions after the decimal. p = q = Expected number of orange-spotted = Expected number of brown-spotted = Expected number of white-spotted =arrow_forward
