Essay

Suppose that a population composed of 100 individuals existed on an island in the Caribbean Sea.Two different alleles of the A gene were present in this population (a¹ and a²)at equal frequency.The following events occurred to this unlucky population.Determine what evolutionary force (mutation,migration,drift,or selection)is represented by each event.In addition,tell the effect of each event on the genetic composition of the population.
a)A devastating fire caused the death of 10 individuals.
b)A disease swept through the island and killed 13 individuals.The a¹ confers resistance to the disease.

d)A ship containing individuals from a different island containing a¹,a²,and a³ alleles landed at the island.
e)The president (whose genotype is a¹a¹)declared that all a¹ individuals had more rights than a² individuals.All a² individuals moved to another island.
f)An individual who was working in a cave stumbled upon a new rock and decided to put it in his pants pockets to show his wife.Some of their babies had an a⁴.
