In pea plants, tallness (T) is dominant to shortness (t). What are the predicted percentages of the genotypes of the offspring if a homozygous short plant is crossed with a heterozygous tall plant?

25 percent Tt, 75 percent tt
25 percent tall, 75 percent short
50 percent Tt, 50 percent tt
50 percent tall, 50 percent short

Answer:

Step-by-step explanation:

In this example, there is a homozygous short plant (tt) and a heterozygous tall plant (Tt).

T t

t Tt tt

t Tt tt

As a result of this cross, 50% of the offspring will be Tt and 50% will be tt.

Hope this helps!
