Eye color in fruit fly is X linked. Here genotype of heterozygous individual will be XRXr and genotype of white eyed individual will be XrY.
a)XRXr-heterozygous, XrY-white eyed
b)50%.
The cross will be as, XRXr × XrY --> [(XR),(Xr)] ×[ (Xr),(Y)] -->XRXr-red,XrY-white,XRY-red,XrXr-white.
So 2 out of 4 are white ,so 50%.

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...

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...

2. Some biology students were checking the eye color for a large number of fruit flies. For the individual fly, suppose that the probability of white eyes is 25 and the probability of red eyes is .75, and that we may treat these flies as independent Bernoulli trials. Suppose that the biology students check the eyes of fruit flies until the third white-eyed fruit fly is observed. (a) What is the probability of observing third white-eyed fruit fly on the...

2. A white eyed female fly (w is a recessive allele of a gene for eye pigmentation on the X chromosome) is crossed with a red eyed male fly. a. Give the genotypes for the parental generation. b. Give the phenotypes and genotypes, and their proportions, for the F1 generation. c.Fls are crossed to one another. Give the phenotypes and genotypes, and their proportions, for the F2 generation.

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 in these flies, pair-wise crosses are performed between each strain. The offspring phenotypes resulting from...

can someone verify this?
In Drosophila, alternate alleles of an X chromosome gene, white, determine red eyes (w') and white eyes (w). Alternate alleles of a second X chromosome gene, yellow, determine brown body ) and yellow body (). In cross series A and B, the F1 females are heterozygous for both genes, but the arrangement of alleles in the parental generation is different in each case. Study the genotypes and phenotypes of the P, F1, and F2 flies in...

6. In Cross 1, a yellow eyed, long wing fruit fly from a pure breeding strain is mated to a red eye, short wing fruit fly from a pure breeding strain. All of their offspring (F1) had red eyes and long wings. In Cross 2, one of the F1 offspring is mated to a fly with yellow eyes and short wings, and this cross gave the following F2 population: 194 flies with long wings and red eyes, 796 flies with...

Which of the following is a correct statement about the phenotype ratios expected for their offspring if the genes are unlinked? A) 9/16 will have brown eyes and red hair B) 9/16 will have blue eyes and red hair...
