Individual barnacles rarely encounter other members of their species B. Large female snails can produce vastly more eggs than small ones. C. Small individual shrimp are less conspicuous to predators.

Merfolk have three pairs of autosomes and one sex chromosome; males are X0 and females are XX. In merfolk the genes controlling tail fin shape and scale colour are on different autosomes. Solid tail fin (Ff) is dominant to forked tail fin (ff), and the F allele is recessive lethal. There are two alleles of the scale colour gene – CB(blue) and CR (red)– CB and CR show incomplete dominance with heterozygotes being purple. The silent trait is X-linked and...

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...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
