Question
. Assume height is controlled by four genes (A,B,C,D). Each gene has two possible alleles. T for tall and t for short. Given the genotypes of the parents below.
FATHER & MOTHER (respectively)

A. Which parent is taller?
B. Could any of their children be as tall as the parents? (If possible, show the genotype of any child that would be the same height.)
C. Could any children be shorter than the parents? (If so, list their genotypes.)
D. Could any children be taller than the parents? (If so, list their genotypes.)
