You set up an experiment in which you breed two populations of true-breeding pea plants. The first true-breeding population has yellow round seeds and the second has green wrinkled seeds. All of the F1 plants yield yellow round seeds. When you self -fertilize the F1 the F2 generation yields a mixture of yellow round, yellow wrinkled, green round and green wrinkled seeds. What does this tell you about the alleles for seed color and shape?

Mendel crossed round and tall pea plants (RRTT) with wrinkle and dwarf ones (rrtt). The F1 plants were all round tall. These F1 plants were cross with rrTt. Which of the following is correct among these offspring?
