Why is Variegation in Four O'clock Plants Determined by the Phenotype

Question

Why is variegation in four o'clock plants determined by the phenotype of the ovule source?
A)Dominant genes demonstrating variegation come from the ovule.
B)The mitochondria determine the leaf coloration,and the mitochondria are inherited through the ovule.
C)Recessive genes demonstrating variegation come from the ovule.
D)The chloroplasts determine the leaf coloration,and the chloroplasts are inherited through the ovule.
E)The ovule nuclear genome contains the genes for leaf coloration.

Accepted Answer

Variegation in four o'clock plants is determined by the phenotype of the ovule source because the chloroplasts, which determine leaf coloration, are inherited through the ovule. Therefore, the answer is D.
