The wild-type eye color of drosophila is dull red, but pure lines with white eyes are available (figure 2-14 ) this phenotypic difference is determined by two alleles of a gene located on the differential region of the x chromosome . Normal inheritance (such as brown eye color, the white-eye phenotype in drosophila does based on our tentative model of inheritance of the white gene. White has been more extensively used than any other character in drosophila, though it is now being used very little because of the fact that the double recessives of white with other sex-linked eye-colors, such as vermilion, are white, and consequently a separation into the true genetic classes is impossible the place of white has been taken .

Researchers have obtained drosophila epilines—that is, genetically identical lineages with distinct epigenetic characteristics—with white, yellow, and red eyes respectively.
“sex limited inheritance in drosophila” morgan found that the genetic factor controlling eye color in the flies was on the same chromosome that determined sex . Simple mendelian genetics in drosophila , the genotypic notation for a mutant gene for white eye color on the x chromosome would look like: determining the .

Transcript of mode of inheritance for eye color in drosophila melanogaster genetic changes can be studied in a few weeks 2 genes involved with eye color white .
Morgan concluded that a fly’s eye color was linked to its sex morgan deduced that the gene with the white-eyed mutation is on the x chromosome, with no corresponding allele present on the y chromosome. Analysis of the inheritance of eye color and wing shape in drosophila melanogaster introduction gregor mendel also known as the father of genetics experimented on pea pants to show the mechanisms of heredity by studying their inherited physical characteristics such as seed shape—round or wrinkled, flower color—purple or white, and seed color—yellow or green.
