Additional recommended knowledge
white was the first sex-linked mutation ever discovered in Drosophila melanogaster. In 1910 Thomas Hunt Morgan, (or, legend has it, his wife) collected a single male white-eyed mutant from a population of Drosophila melanogaster fruit flies, which usually have bright red eyes. Upon breeding this male with wild-type female flies he found that the offspring did not conform to the expectations of Mendelian inheritance. The first generation (the F1) produced 1,237 red-eyed offspring and three white-eyed flies, all males. The second generation (the F2) produced 2,459 red-eyed females, 1,011 red-eyed males, and 782 white-eyed males. Further experimental crosses led Morgan to the conclusion that this mutation was somehow physically connected to the "factor" that determined gender in Drosophila. Morgan named this trait white, now abbreviated w. . Flies carrying the white allele are frequently used to introduce high school and college students to genetics. White-eyed flies are blind.
