Question

The gene for tallness (T) in a pea plant is dominant over the gene for shortness (t).

In a cross between two heterozygous parent pea plants, we can predict that what percentage of the offspring will be tall?

A. 100%
B. 50%
C. 75%
D. 25%​

Answer 1

C

Step-by-step explanation:

Answer 2

C. 75%

Step-by-step explanation:

From a heterozygous cross (Tt x Tt) the produced offspring would consist of:

• 25% TT -it would be tall-.

• 50% Tt -it would be tall as the gene T is dominant-.

• 25% tt -it would not be tall-.

Thus the produced offspring that would be tall is (50% + 25%) 75%. The answer is option C.
