C) genomic imprinting
D) sex linkage

Question

Quizplus · Accepted Answer

The inheritance pattern described by Carl Correns, where the variegated color of leaves in certain plants is determined only by the maternal parent, is best explained by the inheritance of plastid genes. Plastids, including chloroplasts, are cytoplasmic organelles that contain their own DNA and are inherited maternally in most plants. This means that the traits governed by plastid genes are passed from the mother to all her offspring, regardless of the offspring's sex.
