You are trying to calculate the map distances between three genes in Dragonflies. The gene extrawings (ex) produces an extra pair of wings and is recessive to the wild-type four wings (ex+). The gene eyeless (ey) causes the eyes not to form properly and is recessive to the wild-type normal eyes (ey+). The gene blue (b) causes the body to be a neon blue color and is recessive to the wild-type black (b+). A heterozygous dragonfly is crossed to a tester male and the following progeny are obtained: 321 with extra wings and no eyes, 284 with blue bodies, 72 with extra wings, 69 with blue bodies and no eyes, 27 with extra wings and blue bodies, 21 with no eyes, and 4 wild-type.
What is the distance in cM between extrawings and eyeless? (Please answer to two decimal places)
What is the interference?

You are a researcher who is interested in three genes in
drosophila: The a gene, the b gene and the c gene. You think the
genes may be linked, so you decide to do a cross using a
true-breeding a+/b+/c+ fly and an a/b/c fly. The F1 generation is
all a+/b+/c+. However, when the F1 generation is bred to a
true-breeding a/b/c fly, it yields the following offspring
phenotypes: 589 a+/b+/c+ ; 603 a/b/c ; 183 a+/b/c ; 176 a/b+/c+...

5) You are given the task of creating a genetic map of
three genes of Drosophila melanogaster. The genes are all located
on the same chromosome. The genes are for the body color, eye
color, and antenna formation. The alleles for body color are yellow
and gray (wild-type), the alleles for eye color are sepia and red
(wild-type) and the alleles for the antenna are short and normal
(wild-type). The mutant alleles for body and eye color are
recessive, while...

In a three-point testcross, it was found that the genetic map,
for three, linked genes was: A-30 mu-B-20mu-C A genetic cross was
performed and, the outcome was; that of 1000 progeny 1 double
recombinant was observed. How does this compare to what we have
expected? Explain this phenomenon.
