Chapter 3.2, Problem 30AQP

a.

Summary Introduction

To determine:

The copies of the black allele (B) that will be present in each cell of an ${\text{F}}_{\text{1}}$ black guinea pig at the following stages: ${\text{G}}_{\text{1}}$, ${\text{G}}_{\text{2}}$, metaphase of mitosis, metaphase I of meiosis, metaphase II of meiosis, and after the second cytokinesis following meiosis assuming that no crossing over takes place, b. how many copies of the brown allele.

Introduction:

The black fur allele B is dominant and brown fur allele b is recessive in guinea pigs. When a black guinea pig is crossed with a brown guinea pig, five black guinea pigs and six brown guinea pigs are produced in ${\text{F}}_{\text{1}}$ generation.

Summary Introduction

To determine:

The number of copies of the brown allele (b) that will be present in each cell of an ${\text{F}}_{\text{1}}$ brown guinea pig at the same stages as those listed in part a, assuming that no crossing over takes place.
