Question 5Your answer is CORRECT.Genes specifying bitter taste receptors on our tongues have been shown to be polymorphic in many populations. The taste receptor 16 gene is polymorphic for a C or T at site 161 in the San population of Africa. 50 individuals were genotyped with the following outcome: 38 CC, 10 CT, and 2 TT. What is the frequency of the C allele in this population?a) 1.00b) 0.86c) 0.14d) 0.50e) 0.96
Question 6Your answer is CORRECT.Flower color in cypress-vine morning glories (Ipomoea coccinea) is determined by two alleles at a locus. The allele for red color is co-dominant with the allele for white color; heterozygotes are pink. In a population that is in Hardy-Weinberg equilibrium, we count 45 out of 500 individuals that have white flowers. How many individuals do you expect to be red flowered?
24Question 7Your answer is CORRECT.The presence of some wing spots on butterflies is determined by a single locus with two alleles, T and t. TT and Tt individuals have wing spots; tt individuals do not. The presence/absence of wing spots does not affect fitness. In one population, the current frequency of individuals with wing spots is 0.82. AssumingHardy-Weinberg genotype frequencies, what is the probability that the T allele will reach fixation in this population?
Your answer is CORRECT.
