Explain why parental investment (include definition) is fundamental to the evolution of sexual dimorphism and sexual selection? For example, does it determine who is choosy and who competes for mates? Answer this question by only using information from "Evolutionary Analysis" by John C. Herron.

Step 1
Step 1: Parental investment, as defined by Robert Trivers in 1972, predicts that the sex that invests more in offspring will be more selective in choosing a mate, while the sex that invests less will engage in more intra-sexual competition for mates. Show more…

Apart from differential investment in gametes, what other factors might be involved in females being the choosier of the two sexes? Under what circumstances should males be choosy as well?

Differential gene expression (imprinting) has evolved because life-history traits may reflect conflicts of interest between individuals. What would be the conflicts of interest between males and females if a litter or clutch contains offspring from multiple fathers? What should be the effects on natural selection on the individuals of each sex in such litters? How, according to you, could these conflicts affect evolution?
