Question

In pea plants round is dominant to wrinkled. A farmer has a field of round peas. He collects the peas and plants then for the following season. At the end of the following season he harvests 2000 pounds of peas and notices that some of them are wrinkled. List the genotypes of the offspring pea plants. What were the possible genotypes of the parental pea plants?

Answer 1

RR Rr and rr. RR and Rr will look Round. The rr will be wrinkled.

The parent plants were most likely Rr genotypes.

Step-by-step explanation:

Some offspring received two of the R genes. Some received one R and one r, so they will be round too. The offspring with two r genes will be wrinkled, and their offspring will be wrinkled too unless they cross with an RR or Rr parent.
