The fruit fly Drosophila melanogaster as a source of much of the chromosome theory of heredity.

... The fruit fly Drosophila melanogaster as a source of much of the chromosome theory of heredity. ABSTRACT This investigation centres upon the fruit fly Drosophila melanogaster as a source of much of the chromosome theory of heredity. The Drosophila was chosen due to its ease of cultivation within the laboratory as well as the many previous studies performed on it from which information could be drawn. The hypotheses under investigation are: Ho: The inheritance of both wing length and eye colour are not sex-linked. Hi: The inheritance of both wing length and eye colour are sex linked. This was tested by initially crossing three vestigial winged, red-eyed males with four normal winged, white-eyed females. The F1 generation were then allowed to interbreed after their number and phenotypes had been recorded. The F1 generation interbreeding cross consisted of three normal winged, white-eyed males being crossed with four normal winged, red eyes females. The F2 generation produced were
