meriva

Answer:

See the answer below

Explanation:

From the illustration, the yellow color trait is dominant over the green trait.

<em>Assuming that yellow seededness is represented by the allele Y and green seededness by the alleles y. Y is dominant over y, hence a yellow seeded plant would be either YY or Yy while a green seeded plant would be yy.</em>

For a cross between a yellow seeded plant and a green seeded plant to yield all yellow seeded offspring, it means that the parents are YY and yy.

         (yellow)YY    x   (green) yy

F1 progeny: All Yy (yellow)

Now, Yy is crossed with green-seeded plant, yy.

                Yy    x    yy

          Yy    Yy    yy    yy

Hypothesized Genotypic ratio

Yy = 1/2

yy = 1/2

Hypothesized Phenotypic ratio

Yellow seeded = 1/2

green seeded = 1/2
