BIOL 1209 Spring 2011 Writing Assignment 1 Name: Andrew Barker Lab Instructor: Maria Gavilanez Lab Section: 11 General Research Question: A population of the English Peppered Moth, Biston betularia , has developed a mutation in the gene determining color as a response to the pollution in the environment (Kettlewell). This mutation caused homozygous recessive individuals to be black. In the polluted environment, black moths had greater fitness than peppered colored moths (The Peppered Moth), but the environment has recently been cleaned up. This has increased the fitness of the dominant peppered color allele (A) and decreased the fitness of the recessive black colored allele (a). Will the dominant allele (A) be fixed in the population after many generations due to its greater fitness in selection? Null Hypotheses: The null hypotheses states that if the fitness of the dominant allele (A) is greater than the fitness of the recessive allele (a), then the dominant allele (A) will not be fixed in the population despite being selected for.
