Ovules produced by an entirely green plant contain a rare mutation in a nuclear gene that is involved in chlorophyll synthesis, and the gene encodes a nonfunctional protein. Predict the most likely color of the leaves on plants that are produced when these ovules are fertilized by pollen from a wild-type green plant. Provide reasoning to justify your prediction

The plant will produce less chlorophyll

Explanation:

The plant still has a functional allele provided by the paternal gamete, thereby the leaves have this enzyme required for chlorophyll biosynthesis. In consequence, the plant can produce chlorophyll pigment but in less quantity, since it has only a functional allele coding for a key enzyme involved in the chlorophyll pathway
