Question

If the first three F2 offspring grown from the cross described above are round, what is the probability that the next F2 offspring will be wrinkled?

What is the answer to part c) and how? I think the answer is 25% but I am not sure. Please explain why.

Part B Round (R) seed shape is dominant to wrinkled (r) seed shape in pea plants. If an RR plant is crossed with an rr plant, what is the frequency of phenotypes in the F2 generation? View Available Hint(s) All round seeds 3 round seeds, 1 wrinkled seed All wrinkled seeds Previous Answers Correct The F1 generation would have the genotype Rr, so crossing two heterozygotes would result in 3 plants with round seeds and 1 plant with wrinkled seeds. Part C If the first three F2 offspring grown from the cross described above are round, what is the probability that the next F:2 offspring will be wrinkled? View Available Hint(s) 25% 0% 100% 75% Submit

Explanation / Answer

The proportion of rr is 1/4, so the next offspring have 25% chance of beibg wrinkled.
