Genes are segments of dna that determine the phenotype of an individual pee colors can be yellow or green when two plants that produce yellow pee were crossed the offspring produced green peas this is because the parents were blank for pee colors because there are only two options for peace colors the plant peas color is a case of what

I'm a bit confused by this, but let me give it a try:

You have yellow pea plants. But pea plants could be yellow or green.

You cross 2 yellow pea plants you get green and yellow.

First, you have to know that yellow is dominant to green in a pea plant.

So, to think about this genetically, give the traits a letter: Y (yellow), y (green)

Knowing that you get a green pea plant out of a cross of two yellow pea plants says that the original yellow pea plants must be heterozygous so Yy

Do the cross of Yy x Yy

Punnett Square:

      Y       y

Y    YY    Yy

y     Yy    yy

By Genotype, you have 1 YY, 2 Yy and 1 yy

By Phenotype you have 3 yellow and 1 green

So, I think your answer is that the parents were heterozgous for pea color because there are only 2 options for pea color (yellow / green). The green pea plant is a homozygous recessive offspring (yy).

it would be rhyolitic hope this

that scientist would be robert hooke
