Question

1. In humans the presence of chin and cheek dimples is dominant tothe absence of dimples, and the ability to taste the compound PTCis dominant to the inability to taste the compound. Both traits areautosomal, and they are unlinked. The frequencies for dimples are D= 0.62 and d = 0.38. For tasting, the allele frequencies are T =0.76 and t = 0.24.
   1. Determine the genotype frequencies for each gene.
   2. What are the expected frequencies of the four possiblephenotype combinations: dimpled tasters, undimpled tasters, dimplednontasters, and undimpled nontasters?
