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.

What would be the predicted numbers of offspring with the
four genotypes(AaBb,Aabb, aaBb, and aabb) if the parental generation had been AAbb and aaBB instead of AABB and aabb?
