Question

Quizplus · Accepted Answer

The phenomenon being described is chloroplast inheritance. Variegated color in leaves is the result of different chloroplasts in the cells of the plant. Chloroplasts contain their own DNA and are inherited maternally, meaning that only the chloroplasts from the maternal parent are passed on to the offspring. This results in the variegated color pattern being determined solely by the maternal parent.
