In pea plants, yellow seeds are dominant to green seeds. A heterozygous yellow- seeded pea plant (Yy) is crossed with a plant that has green seeds (yy). What
would be the phenotype % in having yellow or green seeds.
Your answer

The phenotypic percentage of having yellow or green seeds is 50% for having either of the two colours

Explanation:

The crossing to determine the offsprings is shown in the image attached where we have two green (Yy) seeds and two yellow (yy) seeds as offsprings.

Thus, the phenotypic percentage of having yellow or green seeds is 50% for having either of the two colours.

Note, the dominant allele is "Y" while the recessive allele is "y". Thus, Yy would produce a yellow colour while yy would produce a green colour (as both mentioned in the question).

Also note that phenotype describes the outward properties/characteristics of an individual.
