B. A sex ratio describes the ratio of males to females in a population.
C. All of these statements are true.
D. An unbalanced sex ratio can leave many individuals without mates.

According to Robert Trivers, why are men generally larger and more physically aggressive than women? Because women are more reproductively “valuable” than men, hence competition for mates is fiercer among men Because men invest more heavily in reproduction than women Because men secrete more testosterone Trivers’ theory does not speculate on the origin of the sex difference in size and physical aggression Although some women are interested in casual sex (short-term mating), research has suggested that there are differences in...

Question 8 1 pts Which of the following is NOT true about sexual selection? Sexual selection operates only on males because they are the ones that compete and females are the "choosy" ones Wb Which types of sexual signals evolve in a given lineage may depend on pre-existing sensory biases (eg. whether individuals can see in color, or what sounds they like) Sexual signals are often "expensive" (in energy, or risks to safety), which means that usually only healthy individuals...
