Answer:
(i) As it is given that plant is heterogeneous for two genes, hence it can be denoted as AaBb. Also, minimum height is 6 feet ( in case of aabb ) while this plant has 20 feet height. This is possible only if each dominant allele contributes height of 7 feet. In case of AaBb, there are two dominant alleles making it's height 6+7+7 = 20 feet.
(ii) the height of plants with genotype
a) AABb - here three dominant alleles are present hence 6+7+7+7 = 27 feet
b) AaBb - here two dominant alleles are present hence 6+7+7 = 20 feet.
