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

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 crossed to aabb individuals.
A. If this cross produces 1000 offspring, what are the predicted numbers of offspring with each of the four genotypes: AaBb, Aabb, aaBb, and aabb7.
B. What would be the predicted numbers of offspring with these four genotypes if the parental generation had been A Abb and aaBB instead of AABB and aabb7.
