The production of eye-color pigment in Drosophila requires the dominant allele A. The dominant allele P of a second independent gene turns the pigment to purple, but its recessive allele leaves it red. A fly producing no pigment has white eyes. Two pure lines were crossed with the following results: P red-eyed female ×white-eyed male 1 F1 purple-eyed females red-eyed males F1×F1 F2 both males and females: (3)/(8) purple eyed (3)/(8) red eyed (2)/(8) white eyed Explain this mode of in

In Drosophila, vermilion eye color is due to a recessive allele (v) located on the X chromosome. Curved wings is due to a recessive allele ( c u ) located on one autosome, and ebony body is due to a recessive allele ( e ) located on another autosome. A vermilion male is mated to a curved, ebony female, and the F1 males are phenotypically wild-type. If these males were backcrossed to curved, ebony females, what proportion of the F2 offspring will be wild-type males? | Numerade

SOLVED:In humans, red-green color blindness is determined by an X-linked recessive allele ( a ), whereas eye color is determined by an autosomal gene, where brown ( B ) is dominant over blue ( b ). a. What gametes can be formed with respect to these genes by a heterozygous, brown-eyed, color-blind male? b. If a blue-eyed mother with normal vision has a brown-eyed, color-blind son and a blueeyed, color-blind daughter, what are the genotypes of both parents and children?

SOLVED: Question 2 In fruit flies, the phenotype for eye color is determined by a certain locus E indicates the dominant allele and e indicates the recessive allele. The cross between a male wild-type fruit fly and a female white-eyed fruit fly produced the following offspring:Wild-type MakWild-type FemaleWhite-eyed MakWhite-eyed FemaleBrown-eyed FemaleThe wild-type and white-eyed individuals from the Fl generation were then crossed to produce the following offspringDetermine the genotypes of th

SOLVED:In Drosophila the ruby eye phenotype is caused by a recessive, X-linked mutant allele. The wild-type eye color is red. A laboratory population of Drosopbila is started with 25 percent ruby-eyed females, 25 percent homozygous red-eyed females, 5 percent ruby-eyed males, and 45 percent red-eyed males. (a) If this population mates randomly for one generation, what is the expected frequency of ruby-eyed males and females? (b) What is the frequency of the recessive allele in each of the sexes?
