Answer 1

Answer:

C. 50%

Explanation:

One of the grapefruit plant is fully white, while the other is heterozygous red:

fully white: bb (If it was BB, then the heterozygous would be white, as it would take on the dominant trait).

heterozygous red: Bb (Red is the dominant trait, denoted by B).

Create the Punnett square:

$\left[\begin{array}{ccc}&b&b\\B&Bb&Bb\\b&bb&bb\end{array}\right]$

As such, the fully white (bb) takes up 50% of the Punnett squre offsprings, which makes your answer C.50%
