A true-breeding strain of peas with round seeds and atrue-breeding strain of peas with wrinkled seeds are crossed.
Their offspring (F1) are allowed to self-fertilize and producean F2 generation. Â
Round pea seeds (F2) were planted and produced mature plantswith flowers.
The pollen from these plants was collected and used to fertilizeplants from the true-breeding wrinkled strain.
a) what proportion of these progeny is expected to have wrinkledseeds?
b) what proportion of these progeny are expected to beheterozygous?
