Question

what are the possible phenotypes of the offspring from the cross above of round seeds (R) are completely dominant to wrinkled seeds (r)? what would the possible phenotypes be if round seeds were incompletely dominant to wrinkled seeds

Answer 1

Assuming that you're talking about two homozygous seeds (RR and rr), 75% of the seeds would be round, and the other 25% would be wrinkled.
