Question 1

Assume that a cross is made between AaBb and aabb plants and that the offspring occur in the following numbers: 106 AaBb, 48 Aabb, 52 aaBb, 94 aabb. These results are consistent with what arrangement of genes?

Question 2

In the fruit fly, Drosophila melanogaster, a spineless (no wing bristles) female fly is mated to a male that is claret (dark eyes) and hairless (no thoracic bristles). Phenotypically wild-type F1 female progeny were mated to fully homozygous (mutant) males, and the following progeny (1000 total) were observed:



a)Which gene is in the middle?
b)With respect to the three genes mentioned in the problem, what are the genotypes of the
homozygous parents used in making the phenotypically wild-type F1 heterozygote?
c)What are the map distances between the three genes? A correct formula with the values
"plugged in" for each distance will be sufficient.
d)What is the coefficient of coincidence? A correct formula with the values "plugged in" will be
sufficient.
