The inheritance of eye color in Drosophila is controlled by
genes on each of the fly?s four chromosome pairs. One eye-color
gene is on the fly?s X chromosome, so the trait is inherited in a
sex-linked manner. For this sex-linked trait, the wild-type (brick
red) allele is dominant over the mutant vermilion (bright red)
allele. A homozygous wild-type female fly is mated with a vermilion
male fly. X+ X+ * X^p Y Predict the eye colors of F1 and F2...

A female fruit fly with vermilion eyes and normal wings is crossed to a male with normal red eyes and cut wings. The F1 progeny consist of females with red eyes and normal wings, and males with vermilion eyes and normal wings. When the F1 progeny are interbred, the F2 consists of two types of females vermilion eyes, normal wings (1/2) and red eyes, normal wings (12), and two types of males-vermilion eyes, normal wings (12) and red eyes, cut...

In Drosophila, the X-linked recessive mutation vermilion (XV) causes bright red eyes, in contrast to the brick-red eyes of wild type (X+). Part A separate autosomal recessive mutation (br), causes the eyes to be brown. Predict the F1 results of the following cross: normal females x white males. (Assume that the parents are homozygous.) Flies carrying both mutations lose all pigmentation and are white-eyed. Label the diagram by dragging the labels to the appropriate targets. Note: not all labels will...

You are working with the fruit fly that generally exhibits a brick red eye color (wild-type). In one stock vial you recover an eye color mutant with brown eyes that you use to eventually derive a pure-breeding brown-eyed stock. Your friend, performing independent studies on the fruit fly, also recovers a pure breeding brown eye color mutant that is phenotypically identical to your strain. How would you go about determining if the two pure-breeding brown-eyed mutant strains represent mutations in...

Drosophila genetics hw. Can someone help explain this
You are doing a genetics experiment with the fruit fly. In the "P" generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. Indicate the alleles associated with dominant phenotypes by uppercase letters and alleles associated with recessive phenotypes by lowercase letters. Assume the genes are...

the fruit fly, Drosophila melanogaster, an allele (v) of the gene vermillion gives flies purple eyes and is recessive to the wildtype red eye color (v+). An allele y of the yellow gene, gives flies a yellow body color compared to the dominant brown body color (yt). A heterozygous females for the two different mutations is test-crossed with mutant (i.e., homozygous recessive) males. The phenotypes of the progeny of this cross and their corresponding numbers are given below Yellow body,...

4.3-4. The gene for eye color in a certain male fruit fly has alleles (R, W). The gene for eye color in the mating female fruit fly also has alleles (R, W). Their offspring receive one allele for eye color from each parent. If an offspring ends up with either (R, R), (R, W), or (W, R), its eyes will look red. Let X equal the number of offspring having red eyes. Let Y equal the number of red-eyed offspring...
