Chapter 9, Problem 5SQ

Summary Introduction

Introduction:

An experiment was conducted which included the cross between the fruit flies leading to the formation of progeny with 77-red eyed males, 71-ruby eyed males and 152 red-eyed females. The gene for the red eye color in drosophila is dominant over the ruby recessive eye color. It is an example of sex linked inheritance in which the alleles of the genes are located at a close distance on the chromosomes. These genes are present on the X-chromosomes and the same traits are passed on to the next generation or the offspring. The Y-chromosome does not exhibit the genes for eye color.
