Chapter 27, Problem 3EQ

Summary Introduction

To review:

The following mentioned frequency and number of sheep for a population sheep, which is in Hardy-Weinberg equilibrium:

The frequency of the white and yellow fat alleles in this population.

The number of sheep with white fat and are heterozygous carriers of the yellow allele.

Introduction:

The Hardy-Weinberg equilibrium describes that the genotypicand allelicfrequencies remains constant, in a populationacross generations, if the evolutionary forces are not present. In its standard form, the equation of Hardy-Weinberg indicates that each individual inherits two replicas of each gene, one from each parent. For a two-allele condition, the equation is written as ${\left(\text{p}+\text{q}\right)}^{\text{2}}=\text{1}$ .
