Question

Round seeds are dominant over wrinkled seeds in pea plants. One parent plant is homozygous wrinkled (rr), and the other parent plant is heterozygous round (rr). Fill in the Punnett square and determine how many offspring will be round and how many will be wrinkled?

Answer 1

The round pea parent plant is heterozygous, and the probability of obtaining three round peas in a random sample of three progeny peas is 1/8.

Step-by-step explanation:

To determine if the round pea parent plant is homozygous dominant or heterozygous, we can use a Punnett square. The round pea parent is heterozygous because all three offspring have round peas. If the round pea parent plant is heterozygous, the probability of obtaining three round peas in a random sample of three progeny peas is 1/8.
