Round seeds (r) are dominant to wrinkled seeds (r), and yellow seeds (y) are dominant to green seeds (y). what is the expected phenotypic ratio of a cross between an rryy and an rryy individual?

The correct answer would be- 1:1:1:1.

Explanation:

According to the question the cross between the two pea plants with the genotype RrYy and rryy where R for round seeds and r for recessive form that expressed wrinkled seed character. The other character of this dihybrid cross is the color of the seds Y for green and y for yellow seeds.

The cross is shown in the image attached that suggests that phenotypic ratio would be 1:1:1:1 as RrYy, Rryy, rrYy, and rryy.

Thus, the correct answer is : 1:1:1:1.
