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: Set up Punnett - square

The genotypes of parents are Rr and rr. The possible gametes from Rr are R and r, and from rr are r and r.

Step2: Fill in Punnett - square

	R	r
r	Rr	rr

Step3: Calculate probability

Out of 4 possible genotypes of offspring (2 Rr and 2 rr), 2 are rr. The probability of getting rr (wrinkled seeds) is $\frac{2}{4}=0.5$ or 50%.

Answer:

50 percent
