Inheritance of Eye Color in Drosophila melanogaster Sex-linked inheritance can lead to remarkable resulting differences between the chromosomes of females and males in many organisms. This study illustrates a simple, yet clarifying experiment designed to determine the sex-linked inheritance in Drosophila melanogaster. Drosophila melanogaster have an x- and a y-chromosome in males and two x-chromosomes in females. The crosses of white-eyed females and red-eyed males give the following outcome in most cases (Figure 1): Figure1(3) In …showed first 75 words of 1175 total…

There was non-random mating within the environment, which helped to increase the number of homozygous individuals, changing the allele frequency. Although the white-eyed trait seemed to virtually disappear, there was no selection in this environment, which further proves microevolution and the fact that eye color is a sex-linked inheritance trait.
