Monohybrid Cross Problem Set

Problem 9: Incomplete dominance

In Mendel's experiments, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would be the result of crossing two Tt plants?

A. 1/4 would be tall; 1/2 intermediate height; 1/4 short

B. 1/2 would be tall; 1/4 intermediate height; 1/4 short.

C. 1/4 would be tall; 1/4 intermediate height; 1/2 short.

D. All the offspring would be tall.

E. All the offspring would be intermediate.
