In a particular plant, three independently assorting genes (Aa, Bb, Cc) influence height, such that each dominant allele adds 4 cm to a base height of 2 cm. The recessive alleles do not add any height. You crossed a AABBcc plant with a AAbbCC plant.

Part A How tall are the F1 plants?

Part B If the F1 plants are crossed, how many different heights would be observed among the F2 progeny? Enter your answer as a single whole number (not word).   cm

What would be the phenotypic ratio among the F2?Enter your answer as whole numbers separated by colons, without any spaces. Do not include any phenotypes or genotypes, but arrange your ratio from shortest to tallest (left to right). For example, for a hypothetical 9:3:3:1 ratio, 9/16 would represent the shortest plants and 1/16 would represent the tallest plants.
