There are three genes that you are tracking on a fruit fly: Gene ‘r’ that results in the phenotype of red body colour Gene ‘t’ for the phenotype of transparent wings Gene ‘b’ for the phenotype of black coloured eyes. You cross breed fruit flies with the above mentioned genes and observe the following: When red body fruit flies are cross bred with transparent winged fruit flies, 2400 offspring were produced. Out of the 2400 offspring,...

2. Three genes and their mutations are found on the third chromosome in fruit fly Drosophila melanogaster. Of these three genes, scarlet eyes (st) are recessive to red eyes (st"), cbony body color (eb) is recessive to gray body color (eb"), and spineless (ss), the st presence of small bristles, is recessive to normal bristles (ss). You eb SS were given a heterozygous fly (st'st eb'eb ss'ss) and were asked to eb ss design an experiment to map the distance...

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...

Question 10 (1 point) In Drosophila, the mutant black (b) has a black body and the wild-type (b+) has a gray body; the mutant vestigial (v) has wings that are short and crumpled compared the long wild-type wings (V+). These genes are linked and are located on the X- chromosome. A cross between a female fly and a black, vestigial winged male fly produced the following progeny: gray (b+), normal (v+) 20 gray (b+), vestigial (v)...

A female Drosophila fly is heterozygous for three recessive pigmentation mutations called pk, bk, and tp.pk is associated with pink eyes, bk is associated with a black body, and tp is associated with transparent wings. A geneticist crosses this fly to a male pink, black, and transparent fly and obtains the 1000 progeny given in the table.

In Drosophila (fruit flies) the genes how, dumpy and ebony are located on chromosome 3. LOF = loss of function. Flies homozygous for a LOF mutation (no gene product made) in ebony have dark black bodies. Flies homozygous for a LOF mutation (no gene product made) in dumpyhave truncated (short) wings. Flies homozygous for a partial LOF mutation (some gene product made but significantly less than normal) in how have wings that will not fold down (held out wings; that's...

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...

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...
