Question

a pea plant that has round seeds has the genotype rr. it is crossed with a pea plant that has wrinkled seeds and the genotype rr. what is the probability that the offspring will have wrinkled seeds?
0 percent
25 percent
50 percent
75 percent

Explanation:

Step1: Determine gametes

The plant with genotype \(Rr\) can produce gametes \(R\) and \(r\). The plant with genotype \(rr\) can only produce gamete \(r\).

Step2: Create Punnett square

	\(R\)	\(r\)

Step3: Calculate probability

Out of 2 possible genotypes (\(Rr\) and \(rr\)), 1 is \(rr\) (wrinkled seeds). Probability \(=\frac{1}{2}= 50\%\)

Answer:

50 percent
