You cross a Drosophila female with kidney-shaped and brown eyes with a male that has wildtype eye shape and color. Kidney-shaped eyes are found in females that are heterozygous for the bar eyed mutation. Bar eyed females are homozygous for the bar eyed mutant allele, whereas bar eyed males are hemizygous for the mutation. Brown eyes are an autosomal recessive mutation. Attention: Half of the resulting F1 has brown eyes! Would you expect to see bar eyed females in the F2?

In a particular trait in Drosophila a cross between a mutant male and wild type female results in all wild type offspring, while a cross between a wild type male and a mutant female produces all mutant offspring. Describe the genetics of the trait.

Bar is a dominant mutation on the Drosophila X-chromosome. A Bar male crossed to a wildtype female giving the following results: Bar females 998 wild type males 1021 wild type female 1 Remember: in Drosophila two X-chromosomes make a female fly and one X-chromosome makes a male; the Y is irrelevant. XXX is lethal. Part I: What are the complete and exact genotypes of each parent and each type of offspring? female parent: male parent:...

32) Normal (wild-type) Drosophila eyes are red. In a cross in Drosophila involving the X-linked recessive eye mutation white (resulting in a white eye) and the autosomal recessive eye mutation sepia (resulting in a dark eye), predict the sex and color of the eyes of the offspring from crossing true-breeding parents for parts A) and B) below. White is epistatic to the expression of sepia (i.e., if an eye is white, it cannot also be sepia; i.e., white masks the...

Parent phenotype: female: apterous and red eyes male: male winged and sepia eyes (note: sepia begins as orange and transitions to gray/black as flies mature) a) Considering both parents are homozygous for each trait, what are the parents' genotypes? b) Using a Punnett square for a dihybrid cross, calculate the genotype and phenotype for the F1 flies. c) With the information obtained from the F1 genotypr, use a Punnett square to calculate the expected genotype and phenotype ratios for the...

Show how the breeding of vermilion/brown, cinnabar/brown, and scarlet/brown double mutant female Drosophila with single mutant scarlet male Drosophila would enable differentiation between the 3 double mutant strains. Show genotypes and phenotypes.

Labrador retrievers are black, brown, or yellow. In a cross of a black female with a brown male, results can be all black puppies, 1/2 black to 1/2 brown puppies, or 3/4 black to 1/4 yellow puppies. What is/are the genotype(s) that results in the black phenotype, brown phenotype, and yellow phenotype?

In the fruit fly, Drosophila melanogaster, a wingless female fly is mated to a male that is white-bodied and legless. Assume that all alleles causing these phenotypes are recessive. Phenotypically wild-type F1 female progeny were mated to fully homozygous (mutant) males, and the following progeny were observed: Phenotypes Number Observed wingless 324 wild-type 34 white, wingless 135 white 8 white, legless 319 hairless, white, legless 32 hairless 140 hairless, legless 9 (a) With respect to the three genes mentioned in the problem, what are the genotypes...

A student crosses a phenotypically wild type Drosophila female to a male with unknown phenotype (that unreliable lab partner confused the fly stocks again!). There are two genes segregating in the cross. The “vg” phenotype has small wings and the “cn” phenotype has light eye color, and both genes are on an autosome. Remember that Drosophila males do not exhibit meiotic recombination. (hint: you may need a page of blank paper to work possible crosses before you answer the questions....

A man and a woman both have brown eyes, but their first child has blue eyes. What are the chances that their second child will have blue eyes? Jane is blood type A and her husband is blood type B. Jane is puzzled because their daughter is type O. Explain how the daughter inherited a blood type neither of her parents has. Jim is blood type A and his mother is blood type O. What are the possible blood types of his father? (Three...

A heterozygous brown-eyed human female who is color blind marries a homozygous brown-eyed male who is not color-blind (remember, color-blindness is sex-linked). Assume that eye color is an autosomal trait and that brown is dominant over blue. a. Write out genotypes of parents and the Punnett squares for the possible offspring below first (Use the table feature to help and clearly label parental and offspring genotypes): *What is the probability that any of the offspring produced have the following traits?
