In a population of Drosophila, an X-linked recessive allele causing yellow body colour is present in genotypes at frequencies typical of random mating. The frequency of the recessive allele is 0.20. Among 1000 females and 1000 males, what are the expected numbers of the yellow and wild-type phenotypes in each sex and what percentage of wild-type females are carriers for the yellow allele?

In Drosophila, cut wings are controlled by a recessive sex-linked allele (ct), and fuzzy body is controlled by a recessive autosomal allele ( fy). When a fuzzy female is mated with a cut male, all the members of the F1 generation are wild-type. What are the proportions of F2 phenotypes, by sex?

In Drosophila, the X-linked recessive mutation vermillion (v) causes bright red eyes, in contrast to the brick-red eyes caused by the wild-type allele. A separate autosomal recessive mutation, brown (bw), causes flies to have brown eyes. Flies with both mutations have no eye pigmentation and are white-eyed. Determine the F1 and F2 phenotypic ratios for each sex from the following crosses: (a) vermillion females X brown males (b) wild-type females X white-eyed males

In Drosophila sable body (sb) and forked bristles (fr) are due to recessive mutations and the genes are linked. These genes are 7 map units (7 m.u) apart. If a true breeding sable body, forked bristles females are crossed a true breeding wild type flies and the F1 wild type looking hybrid females are crossed to wild type looking F1 hybrid males, what fraction (you can use a fraction or percentage for your answer) of the progeny would be just...

Question text In drosophila (fruit flies): The yellow gene is on the X-chromosome, the gene product plays a role in body colour. Wild type flies are a light brown/tan in colour, homozygote yellow mutants have a more yellow shaded body colour. We'll use y+ to represent the wild type allele, and y to represent the mutant allele. y+ is dominant to y. The vestigial gene is on chromosome 2. Homozygote vestigial mutants have very short wings, and cannot fly. We'll...

Color blindness is an X-linked recessive trait in humans. Consider a population in which the X-linked gene that determines colorblindness is in Hardy-Weinberg equilibrium, so assume that the allele frequencies are the same in males and females. If 15% of males in this population have the allele for color blindness, then: (A)what percent of females in the population have normal color vision, but are carriers of the colorblind allele? (B)what percent of females in the population is color blind? (C)what...

In Drosophila, the gene for white (w) eyes is on the X chromosome and it is epistatic over brown and scarlet. White eyes can also result by crossing brown-eyed females (bw) with scarlet eyed males (st) (that is, when both mutant alleles are present). A cross is made between white-eyed females with the genotype w//w (otherwise, homozygous for wild type alleles) and white-eyed males hemizygous for the wild type allele (w+ ). List the expected: a) Genotypes of the P1...
