Evolution is one of the unifying themes of biology Evolution involves change in the frequencies of alleles in a population For a particular genetic locus in a population the frequency of the recessive allele a is 0 4 and the frequency of the dominant allele A is 0 6 a What is the frequency of each genotype AA Aa aa in this population What is the frequency of the dominant phenotype b How can the Hardy Weinberg principle of genetic equilibrium be used to determine whether this population is evolving c Identify a particular environmental change and describe how it might alter allelic frequencies in this population Explain which condition of the Hardy Weinberg principle would not be met d In fruit flies Drosophila melanogaster straight wing shape is dominant to curly wing shape A particular population of fruit flies is in Hardy Weinberg equilibrium with respect to the alleles for wing shape The Hardy Weinberg equation given below is useful in understanding population genetics p 2pq q 1 Explain what the terms p 2pq and q represent in the population of fruit flies
