Chapter 9, Problem 11SQ

Summary Introduction

To explain: The determination of the genotype of one brown F₂ mice in problem 10, the analysis whether a brown mouse is homozygous or heterozygous.

Introduction: There are two alleles for a gene which express the brown color in mice. The gene for the brown color in mice is depicted by B, which is a dominant gene and the allele for the recessive gene is depicted by b. The genotype of the dominant homozygous brown mouse will be BB and the genotype of the dominant heterozygous brown mice will be depicted by Bb in the ${\text{F}}_{\text{2}}$ generation.
