Female Drosophila with cinnabar eye (cn) and vestigial wings (vg) were mated to males with roof wings (rf). The F1 were all wild-type. When the F1 females were test crossed with males homozygous for all three traits the following result were obtained.

For this problem, rf cn vg is for roof wing / cinnabar eye / vestigial wing

rf + cn + vg + all wild (no definite phenotype described)

Give the genotype of the offspring (this time simply follow the given sequence above and separate the genes with single space)

F2:

Phenotype	Frequency	Genotype
cinnabar, vestigial	382
roof	401
cinnabar	3
roof, vestigial	4
roof, cinnabar, vestigial	59
Wild	67
roof, cinnabar	44
vestigial	40

2. Give the phenotype and genotype of the female parent:

phenotype: ____

genotype: _______

3. Give the phenotype and genotype of the male parent:

phenotype: _______

genotype: _______

5. Give the calculated map distance in:

Region I: ______

Region II: _______
