Question

Two genes are located on the same chromosome and are known to
be 12 mu apart. An AABB individual was crossed to an aabb individual
to produce AaBb offspring. The AaBb offspring were then
testcrossed to aabb individuals.
If the testcross produces 1000 offspring, what are the predicted
numbers of offspring with each of these four genotypes: AaBb,
Aabb, aaBb, and aabb?
