In Drosophila the gene for red eyes is dominant over the gene cinnabar eye color, the gene for gray body color over the genome of the black color of the body, the gene for normal wings – on the genome of rudimentary wings. All the genes are on the same chromosome. After crossing a homozygous female Drosophila with red eyes (cn+), gray body (b+) and normal wings (vg+) with a homozygous recessive male with cinnabar eyes (cn), black body (b) and rudimentary wings (vg), heterozygous offspring were obtained. An analysis of crossbreeding was performed with a hybrid female from F1. As a result, there were 1,540 flies of 8 phenotypes: 631 red-eyed gray with normal wings, 575 black wingless with cinnabar eyes, 1 red-eyed black wingless, 2 gray with normal wings and cinnabar eyes, 91 red-eyed gray wingless, 80 black with normal wings and cinnabar eyes, 68 red-eyed black with normal wings, 56 gray wingless with cinnabar eyes. Record the progress of crosses. Determine the distance between genes and their order.

5. The eye color gene in fruitflies is located on the X chromosome. The dominant wild-type X^+ allele produces red eyes, while the recessive XW allele produces white eyes. In addition, sex is determined in fruitflies by the ratio of the number of X chromosomes to number of sets of autosomes. Imagine that a pure-breeding white-eyed female with the genotype X^W X^W Y AA mates with a pure-breeding red-eyed male who has the genotype X^+ Y AA. Imagine that nondisjunction...

Cinnabar eyes (cn) and reduced bristles (rd) are autosomal recessive characters in Drosophila. A homozygous wild-type female was crossed to a reduced, cinnabar male, and the F1 males were then crossed to the F1 females to obtain the F2. Of the 400 F2 offspring obtained, 292 were wild type, 9 were cinnabar, 7 were reduced, and 92 were reduced and cinnabar. Briefly explain (2 sentences) these results and estimate the distance between the cn and rd loci.

32) Normal (wild-type) Drosophila eyes are red.

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...

Bar eye (B) is a dominant and sex-linked trait of Drosophila. Curved wings (cu) and black body (bl) are recessive traits, both found on chromosome 2, separated by 24 map units. A homozygous Bar-eyed, black-bodied female is crossed to a true-breeding male expressing curved wings. The heterozygous F1 female is then crossed to a male expressing all three traits. At what frequency among the F2 would you expect to find a completely wild type male? How often would you find...
