Question:

The height of a type of bean plants is determined by five unlinked genes called A, B, C, D, and E. Each gene has two alleles: additive (uppercase letter) and nonadditive (lowercase letter).
The shortest plants are 130 cm. The tallest plants are 220 cm. Estimate how many centimeters each allele contributes to the height difference of 90 cm.

Answer:

They average in a contribution of 18 centimeters each, however it is unlikely that the genes work in a way that is quite so clear-cut. It is more likely that some alleles are more important than others for determining plant height and affect the plants to varying degrees.
