Chapter 3, Problem 43.8P

Summary Introduction

To explain: The F1 and F2 generations by a cross between a pure line female Drosophila with brown eyes and short wings and a male from a normal pure line.

Introduction: Each gene has two types of alleles, a dominant and a recessive. In Drosophila melanogaster, the dominant red eye color masks the effect of recessive brown eye color. Similarly, the allele for the long wings masks the effect of an allele that codes for the short wings.
