Answer

Explanation:

Step1: Determine the gametes

The plant with genotype ( Rr ) can produce two types of gametes: ( R ) and ( r ) (each with equal probability). The plant with genotype ( rr ) can only produce ( r ) gametes.

Step2: Create a Punnett square

( R ) ( r )
( r ) ( Rr ) ( rr )
( r ) ( Rr ) ( rr )
From the Punnett square, we see that out of 4 possible combinations, 2 are ( rr ) (which gives wrinkled seeds) and 2 are ( Rr ) (which gives round seeds).

Step3: Calculate the probability

The probability of getting ( rr ) (wrinkled seeds) is ( \frac{2}{4} = 0.5 ) or 50 percent.

Answer:

50 percent (corresponding to the option "50 percent")
