Suppose that you are working with flies that are segregating three traits. You cross a homozygous truncated, vestigial, shaven fly with a homozygous wild-type, apterous, spineless fly and the F1 flies are all wild-type, apterous, spineless. You next backcross the F1 flies to a truncated, shaven, vestigial parent. The progeny from this type of cross are shown below:

truncated apterous shaven 94

truncated vestigial shaven 425

truncated apterous spineless 46

truncated vestigial spineless 19

wild-type apterous shaven 16

wild-type vestigial shaven 46

wild-type apterous spineless 448

wild-type vestigial spineless 106

Total 1200

Draw a map and show the distances between the three genes.

A parental cross between homozygous cinnabar flies (cnbw+/cnbw+) and homozygous brown flies (cn+bw/cn+bw) is done. Use a Punnett square to show how the F1 cross will not produce homozygous double mutant flies in the F2 generation.

If you have P generation where one parent is homozygous dominant for both traits and the other parent is homozygous recessive for both traits, what will the F1 genotypes be? If you then cross F1 x F1, what will the F2 genotypes be? Assuming that the trait is one of “complete dominance”, what will be the F2 frequency of offspring with 1) both dominant traits, 2) one trait dominant and one trait recessive, 3) one trait recessive and one trait...

Mapping traits to a chromosome Fruit flies have four chromosomes. Fruit flies also have a number of body markers that are useful for mapping genes to given chromosomes. Chromosome I is the X chromosome, which has eye color alleles w+ (red eyes, dominant) and w- (white eyes, recessive). Curly O (Cyo), located on chromosome II, is a dominant marker mutation which causes the wings to curl on the ends instead of beings straight (WT). Stubble (Sb), a dominant marker mutation...

2. Cross a homozygous tall yellow seeded plant with a homozygous short green seeded plant. This is called the P1 cross, and it will produce offspring called the F1 generation. Tallness is dominant to shortness, so use a capital T to represent the tallness allele and lower case t to represent the shortness allele. Yellow seeds are dominant to green sees, so use a capital Y to represent the yellow seed allele and a lower case y to represent the...

how and dumpy interact such that flies who are homozygous for the dumpy LOF mutation (dp) and heterozygous for the complete LOF mutation of how (h-) have wild type wings (normal length). Mutants when dealing with only one gene (wildtype/normal phenotypes are dominant to mutant phenotypes): dp/dp = truncated (short) wings h-/h- = dies when trying to exit pupae Mutants with the two genes interacting (wildtype/normal phenotypes are dominant to mutant phenotypes; so if there is even one dp+ allele...

Suppose that we cross two flies: One is a female that is b+b vg+vg; the other is a male that is homozygous recessive. The female has grey (wild-type) body and normal (wild-type) wing length. The male is black-bodied with vestigial wings. The female's parents (I'm going to refer to them as the grandparents) were a true-breeding grey, normal fly and a true-breeding black, vestigial fly. A) What is the frequency of phenotypes you would expect to see in their offspring?...
