pea plants with yellow peas are crossed. Most of their offspring have yellow peas, but about 25 percent of the offspring have green peas. For pea color, yellow is the dominant trait and green is the recessive trait. What does this tell you about the two parent plants?

Hello!

Yellow = Y

Green = y

Based on the fact that 25% of the offspring inherited two recessive alleles (we know this because in order for a recessive allele to be expressed, it must be homozygous), the parent peas had to both be heterozygous.

Yy * Yy will always result in:

1/4 = yy

2/4 = Yy

1/4 = YY

I hope I helped!

Answer: the answer is "The parent plants are heterozygous for pea color."
