Required information Fruit flies normally have red eyes. Seven different true-breeding strains of fly with white eyes have been identified (A-G). In each strain, the white eye trait is due to an autosomal recessive allele. It is possible all seven strains have mutations in the same gene. Alternatively, they may have mutations in different genes. To determine how many genes are involved in eye color...

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...

You are interested in mouse eye development and conduct a genetic screen for mutations that result in strong eye defects. After treating a male mouse with ENU (a chemical mutagen that induces base-pair changes and small deletions), you identify four mouse mutants 1-4, each with defective eyes. You cross each of the four mutant mice with eye defects to homozygous wild type mice and examine the progeny from each cross. What type of information can you get from observing the...

In Drosophila, the autosomal recessive brown eye color mutation
(b) displays interactions with both the X-linked recessive
vermilion mutation (v) and the autosomal recessive scarlet (s)
mutation. Flies homozygous for brown and simultaneously hemizygous
or homozygous for vermilion have white eyes. Flies simultaneously
homozygous for both the brown and scarlet mutations also have white
eyes. Flies that are wildtype at all 3 loci have wildtype eye
color. Flies that are homozygous or hemizygous for the recessive
mutant at only one...

Normal eye color in flies is red. Mutant flies have brown eye color. Similarly, normal wing length is long. Mutant flies have short wings. A female true breeding fly with brown eyes and short wings is crossed with a true breeding male with red eyes and long wings. In the F1 the female flies are red eyed and long winged. The male flies are red eyed and short winged. F1 males are crossed to F1 females Both sexes of F2...

In the Australian sheep blowfly an autosomal gene yellow (alleles y, y + ) determines the recessive phenotype yellow eyes. A pure breeding strain with yellow eyes is crossed to a pure breeding wild-type strain. The F1 flies from this cross are allowed to interbreed to produce the F2 generation. 41 The phenotype of the F1 flies will be A. wild type B. yellow eyes C. recessive D. y + y 42 The F1 flies are testcrossed, the phenotypic ratio...

29, In fruit flies, red eyes are dominant over white eyes. The gene for eye color (R) is found on the X chromosome (X^R). Females have 2 X chromosomes and males are XY. Fill in the following (case sensitive!): Genotype of a white eyed female: Possible female gametes; separate gametes with a comma (,): Genotype of a red eyed male: Possible male gametes; separate gametes with a comma (,): In fruit flies, red eyes are dominant over white eyes. The...
