Mutant Trait of Drosophila melanogaster The mode of inheritance for the mutant trait giving a dark dark body phenotype was determined using Drosophila melanogaster. This phenotype was determined to be result of the ebony mutant trait. An initial mating was set up between homozygous mutant males, and homozygous normal virgin females. The F1 generation was examined and then allowed to self cross. Then the resulting F2 generation was examined and the frequency of the mutant …

…generation which consisted of 98 flies, had 74 normal flies and 24 mutant flies. Both groups contained males and females. This yielded X2=.0136; P>.95; D.F. = 1 which supported the hypothesis of autosomal recessive inheritance. REFERENCES 1. Shorrocks, Bryan. Drosophila, Ginn and Company Limited: London, 1972. 2.
