question 82

Essay

A plant has green leaves with multiple yellow spots. When used as an egg donor in a cross with a normal plant that has all green leaves, some of the progeny have green and yellow leaves and some have all green leaves. When used as the pollen donor in a cross with a normal plant, all the progeny have all green leaves. One of the progeny with green and yellow leaves has one branch with all green leaves and one branch with all yellow leaves. A flower on the all-green branch is fertilized with pollen from a flower on the all-yellow branch. Predict the results of this cross and the reciprocal cross.
