Answer:
This is because the parents were heterozygous for pea color.
Because there are only two options for pea color the plants pea color is case of simple Mendelian genetics.
Explanation:
In a cross involving homozygous recessive parents or homozygous dominant parents, all the offsprings will be homozygous recessive or homozygous dominant respectively.
Thus crossing of yellow seeded pea plants will produce yellow seeded pea plants only. But here green seeded pea plants are produced which suggests that the parents are heterozygous.
Only when both parents are heterozygous, a trait different from that of the parents will be expressed in the offspring. Here there are only two options for seed color green and yellow . Thus this is a case of simple Mendelian genetics.
