Genetic Linkage The six genes listed below are all located on Chromosome 2 of Drosophila melanogaster. Your goal is to construct a genetic map of Chromosome 2. That is, determine the order of these genes along chromosome 2 and the map distance in centimorgans between each gene. To complete this task, you will be given the results of a variety of two-point test crosses involving these genes. For each test cross you may assume that the female is heterozygous and...

the fruit fly, Drosophila melanogaster, an allele (v) of the gene vermillion gives flies purple eyes and is recessive to the wildtype red eye color (v+). An allele y of the yellow gene, gives flies a yellow body color compared to the dominant brown body color (yt). A heterozygous females for the two different mutations is test-crossed with mutant (i.e., homozygous recessive) males. The phenotypes of the progeny of this cross and their corresponding numbers are given below Yellow body,...

In the Australian sheep blowfly an autosomal gene yellow (alleles y, y + ) determines the recessive phenotype yellow eyes. A pure breeding strain with yellow eyes is crossed to a pure breeding wild-type strain. The F1 flies from this cross are allowed to interbreed to produce the F2 generation. 41 The phenotype of the F1 flies will be A. wild type B. yellow eyes C. recessive D. y + y 42 The F1 flies are testcrossed, the phenotypic ratio...

In Drosophila, purple eyes (pr) are recessive to wild type red eyes (pr+), and forked bristles (1) are recessive to wild type bristles (fº). A pure breeding purple eyed, forked bristled fly was mated to a pure breeding red eyed, wild type bristled fly. The resulting F1s were crossed to true breeding purple eyed, forked bristled fly, and the following offspring were observed: 322 red eyed, wild type bristles 318 purple eyed, forked bristles 78 red eyes, forked bristles 82...

5. In Drosophila, males from a true-breeding stock with raspberry-colored eyes were mated to females from a true-breeding stock with sable-colored bodies. In the F1 generation, all the females had wild-type eye and body color, while all the males had wild-type eye color but sable-colored bodies. When F1 males and females were mated to each other, the F2 was composed of: 216 females with wild-type eyes and wild-type bodies 223 females with wild-type eyes and sable bodies 191 males with...
The genes for sepia eye color, short bristles, and dark body coloration are on the same...
The genes for sepia eye color, short bristles, and dark body coloration are on the same chromosome of Drosophila melanogaster. Each gene has two alleles: wild type, which is dominant, or mutant, which is recessive. se+ is dominant and causes red eyes; se is recessive and causes sepia eyes sb+ is dominant and causes long bristles; sb is recessive and causes short bristles b+ is dominant and causes gray body coloration; b is recessive and causes dark...

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...

A female fruit fly who is heterozygous with the phenotype gray body, red eyes & long wings is crossed with a male who is homozygous recessive (black body, purple eyes, vestigial wings). The observed offspring are shown below: # offspring, body color. eye color. wing length 411 gray red long 61 gray red vestigial 2 gray purple long 30 gray purple vestigial 28 black red long black red vestigial...

BIO340 Recitation 5 Spring 2020 Your professor is having you look at two genes in Drosophila fruit flies to determine experimentally whether they are linked. One trait is eye color and two alleles are present at the gene: se+ is the wild-type allele for red eyes, and se is the mutant, recessive allele for sepia eyes. The second trait is body color and two alleles are present at this gene: e+ is the wild-type allele for grey body, and e...
