When second-generation round pea plants (each of which carries both r and r genes) are crossed, find the probability that a third-generation offspring will have (a) round peas and (b) wrinkled peas?

Since both generations are both round (r) that means the thrid generation will have round peas. The probabilty for the third generation to have round peas is 100% and the probablity for the third generation to have wrinkled peas is 0%.
So your answer is A

The probability of having round peas in the third generation is 100%, because both the genes are of round peas, if they are crossed, only round peas will come in the third generation.

What is crossing over?

Crossing over is a process that happens in meiosis. The process involves the pairing of chromosomes that are similar. The one chromosome is of the mother and the father.

The crossing over here is happening between two r, both are of round genes. So, the result will be round in the third generation.

Thus, due to the fact that both genes are those of round peas, there is a 100% chance that only round peas will be produced in the third generation if they are crossed.
