Question 23
Using the data above, consider the numbers of females and males in 1980. Which sex do you predict to be under stronger sexual selection? Defend your answer.
Question 24
Given your prediction in Question 23, describe the possible consequences of this sexual selection on both the male and female G. fortis. What types of phenotypic changes or differences would you predict would arise?

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”.?

Introduction The Island of Daphne Major, one of several islands that make up the archipelago of islands off the coast of Ecuador, supports a population of ground finches, Geospiza fortis. Finches are small songbirds with chunky beaks which they use to crack open seeds from various shrubs and trees on the island. These seeds make up most of the finch diet. Biologists have been studying this population for over 30 years. Each...
