1. The ability to taste the compound PTC is controlled by a dominant allele T, while individuals homozygous for the recessive allele (t) cannot taste PTC. In a population consisting of 500 individuals, 347 are tasters and 153 are non-PTC tasters. Calculate the frequency of the T and t alleles in this population, and frequency of the genotypes.(Please train yourself to use the Hardy-Weinberg equation.)To present your answers, follow the format in the picture below.

The common garden pea (Pisum sp.) can have green or yellow pea pods. Green peas are either homozygous dominant or heterozygous, while yellow peas are homozygous recessive. In a population of 500, there are 150 yellow individuals. Calculate q, p, p^2, 2pq, q^2.Then determine the number of mottled and orange individuals in the population. Select all the answer below that are correct. Note p? and p^2 are equivalent notation.
26. Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant.
