Two autosomal genes in drosophila code for eye color and wing shape (the wild type is dominant). the genetic symbols for these traits are for eyes: pr: purple and pr+: red and for wings vg: vestigal and vg+: normal. a. what are the genotypes of a pure-breeding purple vestigial fly and a purebred red normal fly? b. what do we get if we cross these two pure-breeding lines? give the genotype and the phenotype. c. what would you expect if you test-cross these f1's? d. which alleles are from the test-cross individual? e. the results that morgan got were not what you would expect. instead, he saw fewer of the purple normal (pr pr vg+ vg ) and red vestigial (pr+ pr vg vg). what do these results tell us about the gametes produced by the original heterozygote? f) how did morgan explain these results?
