Explanation:

Step1: Identify gamete genotypes

Parent 1 (Rr): produces $R$ and $r$ gametes.
Parent 2 (RR): produces $R$ gametes only.

Step2: Create Punnett square

	$R$	$r$

Step3: Count heterozygous offspring

Heterozygous genotype is $Rr$. Out of 2 total possible genotypes, 1 is heterozygous.

Step4: Calculate percentage

$\text{Percentage} = \frac{1}{2} \times 100 = 50$

Answer:

50
