WebScience Biology In Drosophila, white eyes is a sex-linked and recessive to red (wild type) eyes. Short wings is an autosomal recessive condition. A female, heterozygous for eye color and for wing length is mated with a male that has red eyes and is homozygous for long wings. List the predicted phenotypic ratio among offspring from this mating. WebThe white eyed male (w) was mated with a homozygous red eyed female (WW) as shown in Fig. 5.42. Fig. 5.42. A diagram showing two generations of the inheritance of a trait controlled by a gene located on the X chromosome of Drosophila. The gene in this case controls the production of white eye colour; its normal allele results in red eye colour. certificate warning outlook.office365.com WebOct 26, 2024 · What gene is mutated in white eye flies? The Drosophila gene w (CG2759) is a central part of the eye-pigmentation pathway. It encodes an ATP binding cassette transporter, White (O’Hare et al., 1984; Pepling and Mount, 1990), that forms dimers with either Brown or Scarlet proteins, encoded by brown and scarlet genes respectively.
