White eye = Recessive = Xw
Red eye = Dominant = XW
White eyed female = XwXw
Red eyed male = XWY
Parental cross: XwXw X XWY
F1 progeny:
XWXw = Red-eyed female (Carrier)
XwY = White-eyed male
F1 selfing: XWXw X XwY
F2 progeny:
XWXw = Red female (Carrier)
XWY = Red male
XwXw = White female
XwY = White male

2.In Drosophila, yellow body is due to an X-linked gene that is recessive to the gene for gray body. (a) A homozygous gray female is crossed with a yellow male. The F1 are intercrossed to produce F2. Give the genotypes and phenotypes, along with the expected proportions, of the F1 and F 2 progeny. (b) A yellow female is crossed with a gray male. The F1 are inter- crossed to produce the F2. Give the genotypes and phenotypes, along with...

Miniature wings in Drosophila melanogaster result from an X-linked gene (Xm) that is recessive to an allele for long wings (X+). Sepia eyes (s) are produced by an autosomal gene that is recessive to an allele for red eyes (s+). A female fly that is true-breeding for long wings and sepia eyes is crossed with a male that is true-breeding for miniature wings and red eyes. The F1 are intercrossed to produce the F2. 1) What are the expected genotypic...

A (w-/ w-) white-eyed Drosophila female is crossed with a red-eyed male. Assuming the trait for eye color is sex-linked, what are the possible phenotypes of the progeny? All red-eyed individuals Red- and white-eyed females and males Only red-eyed females and white-eyed males Both red- and white-eyed males and only white-eyed females None of these

2. A female Drosophila of unknown genotype was crossed with a white-eyed male fly, of genotype (w = white eye allele is x-linked recessive, W+= red-eye allele is dominant.) Half of the male and half of the female offspring were red-eyed, and half of the male and half of the female offspring were white-eyed. What was the genotype of the female fly?

If an apterous female fruit fly with wild type (+) red eyes is crossed with a white eyed male with normal wild type wings, what is the resting F1 generation? Please show on a punnet square.Also what is the punnet dihybrid cross for the F2 generation. Note: the recessive white eyed allele is X-linked while the apterous (wingless) recessive allele is NOT x-linked. SO to summarize: male with recessive white eyes and with normal wild type wings and a recessive...

A female drosophila fly is homozygous for a null allele of the X-linked white gene. Nondisjunction of the X chromosome occurs in meiosis I in this female fly. If this female fly mates with a red-eyed male fly, what is a possible exceptional progeny genotype? Group of answer choices A. Xw Y Y B. Xw XwY C. Xw+ Xw Y D. Xw+ Xw+ Y E. Xw+ Xw+ Xw

717 pts). In Drosophila, two recessive mutations delta vein (d) and rough eye (r) both map to chromosome 3 and are known to be 20 m.u. apart. Another recessive mutation, garnet eye color (a) has been mapped to the X chromosome. A delta veined, rough and garnet eyed- female was crossed to a wild-type male.

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...

what would f1 and f2 offering phenotypes be when crossing a white eyed female fruit fly with a wild type/red eyed male? in f1 I got all males white eyes and all females red eyes. f2 hasnt hatched and would like to know what to expect. thank you.

EXTRA CREDIT (10 pts) 7) In Drosophila, white eye is an X-linked recessive trait and ebony body is an autosomal recessive trait. A homozygous white-eyed female (normal body) is crossed with a homozygous ebony male (normal, red eyes). a) What phenotypic ratio do you expect in the F1 generation? Show your work. b) What phenotypic ratio do you expect in the F2 generation? Show your work.
