Question

What should you expect to observe if a pea plant that is homozygous

dominant for a certain trait is crossed with a pea plant that is homozygous
recessive for that trait?
O A. All of the plants in the F₂ generation will have the recessive trait.
OB. All of the plants in the F₂ generation will have the dominant trait.
OC. All of the plants in the F₁ generation will have the dominant trait.
O D. All of the plants in the F₁ generation will have a combination of the
two traits.

Answer 1

When a pea plant that is homozygous dominant (let's denote it as DD) for a certain trait is crossed with a pea plant that is homozygous recessive (denoted as dd) for that trait, you would expect the following in the F1 generation:

All of the plants in the F1 generation will have the dominant trait (D). This is due to the dominant allele (D) masking the expression of the recessive allele (d).

So, the correct answer is:

OC. All of the plants in the F1 generation will have the dominant trait.
