Design and conduct an experiment to evaluate whether the red eye trait in the fruit fly, Drosophila melanogaseter, is dominant or recessive, autosomal or sex linked.
Figure 12.2E.112.2�.1: Eye color in Drosophila is an example of a X-linked trait: In Drosophila, the gene for eye color is located on the X chromosome. Clockwise from top left are brown, cinnabar, sepia, vermilion, white, and red. Red eye color is wild-type and is dominant to white eye color.
Figure 12.2E.112.2�.1: Punnett square analysis of Drosophila eye color: Punnett square analysis is used to determine the ratio of offspring from a cross between a red-eyed male fruit fly (XWY) and a white-eyed female fruit fly (XwXw).
