Answer

Answer:

D. 1 RR: 2 RW: 1 WW

Explanation:

Step1: Determine the gametes

Each pink - flowered plant (RW) produces R and W gametes.

Step2: Create a Punnett square

$$ \begin{array}{|c|c|c|} \hline & R & W \ \hline R & RR & RW \ \hline W & RW & WW \ \hline \end{array} $$

Step3: Count genotypes

From the Punnett square, there is 1 RR, 2 RW, and 1 WW. So the genotypic ratio is 1 RR: 2 RW: 1 WW.
