A pure-breeding fruit fly with curled wings mates with a pure-breeding fruit fly with normal (straight) wings. The F1 mate with each other to produce an F2 generation that consists of 160 flies with curled wings and 80 with straight wings. What can you infer from this observation? A. Wing shape is controlled by two codominant alleles. B. All of the hybrid F1 flies had straight wings C. Two interacting genes determine wing shape. D. The dominant curled wing allele is also a recessive lethal E. Curled wings is a recessive trait.

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...

You make cross between a male fruit fly with wrinkled wings and a female fly with vestigial wings. All of the F1 flies are have wrinkled wings. A cross between an F1 female fly and an F1 male fly yields the following offspring: 45 wrinkled-wing males 51 wrinkled-wing females 18 vestigial-wing males 14 vestigial-wing females What do you hypothesize as the mode of inheritance for this trait?

Assortment of genes on same chromosome In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another gene locus. there is a dominant gene for red eyes and its recessive allele for purple eyes. A female that was heterozygous at both gene loci was mated with a male that is homozygous for both recessive alleles. Knowing this, complete the sentences with the correct terms. 94% crossing over independent assortment...

E10 from Brooker: In fruit flies, curved wings are recessive to straight wings, and ebony body is recessive to gray body. A cross was made berween true-breeding flies with curved wings and pray bodies and flies with straight wings and ebony bodies. The F1 offspring were then mated to flies with curved wings and ebony bodies to produce an F2 generation. A. Diagram the genotypes of this cross starting with the parental generation and ending with the Frencration B. What...

Drosophila genetics hw. Can someone help explain this
You are doing a genetics experiment with the fruit fly. In the "P" generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. Indicate the alleles associated with dominant phenotypes by uppercase letters and alleles associated with recessive phenotypes by lowercase letters. Assume the genes are...

3-3. In the fruit fly, Dichaete (D) is a dominant autosomal mutation that affects wing shape; it is lethal when homozygous. Ebony body, e, and rose eye, r, are recessive mutations also located on the same chromosome. Dichaete flies were crossed to pure-breeding ebony, rose flies. Among the F1 were Dichaete progeny with normal body and eye color. Female Dichaete F1 were test-crossed to ebony, rose males, with the results listed below. (Show your work!) A. Write the genotypes of...

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...

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...

recalling that wild type is tan body, red eyes, straight wings and

hypothesis that mutant trait-pick a mutant-is -autosomal or
sexlinked-, -dominant or recessive-.
using the f2 geb data and assuming we want to fail to reject the
null hypothesis abd support "logical" hypothesis for this mutant
trait, for the chi square goodness of fit test what is the chi
