5. In a given population of diploid individuals, two alleles of gene A exist, A and a. Gene A DNA from 100 individuals is amplified and the PCR products are sequenced to determine which allele(s) each individual has (their genotype). The results demonstrate that the sample is made up of 16 AA, 48 Aa, and 36 aa individuals. What is the number of A alleles in this sample? What is the total number of chromosome copies sampled? What is the A allele frequency in this sample? What is the a allele frequency in this sample? a. b. C. d. 6. In a population of 400 salamanders, some individuals have long toes and others have short toes. This phenotypic difference is due to a single gene with dominant and recessive alleles, T and t, where T confers long toes. If the toe length gene is in Hardy-Weinberg equilibrium, and 256 individuals have short toes, how many individuals are heterozygous at the toe length locus? a. 144 b. 128 c. More information is needed to determine the answer.
