fruit flies, you are studying three genes, whose recessive alleles can generate interesting traits. The abnormal traits are “short” – gene s, “ruby-eyed” – gene r, and “ebony body” – gene e. You have been provided an F1 population of flies that are heterozygous at all three of these gene and you testcross these flies by “ssrree” flies. The attached image lists any recessive traits displayed by the flies, unlisted traits are wild type. d) develop a genetic map for this locus, noting your calculated map distances. e) If possible, calculate interference
