Ascientist pollinates a true-breeding pea plant with violet, terminal flowers with pollen from a true-breeding pea plant with white, axial flowers. which of the following observations would most accurately describe the f2 generation?
75% violet flowers; 75% terminal flowers
75% white flowers in a terminal position
75% violet flowers; 75% axial flowers
75% violet flowers in an axial position

75% violet flowers; 75% axial flowers

Explanation:

In pea plants, Mendel discovered that the violet color of the flowers corresponds to a dominant allele over the white color. And axial flowers are dominant over terminal flowers.

I will represent with the letter V the color of the flower. (V) for the dominant allele and v for the recessive. The same with the position of the flower. (A) for the dominant color and (a) for the recessive.

-true-breeding pea plant with violet, terminal flowers  = VVaa

-true-breeding pea plant with white, axial flowers = vvAA

These two are the parental plants (P) when they cross PxP the only way that the alleles are segregated is that each of the F1 have the following conformation = VvAa (F1)

To find out how the F2 generation is going to be, we can make a Punnett table (attached the chart)  where we will cross two individuals of the F1 generation (F1 X F1).

As a result 75% of the plants will have violet flowers and 75% axial flowers

the answer to your question is:
