Question

Quizplus · Accepted Answer

Maternal-effect genes (also called egg-polarity genes) affect the maternal tissue that contributes to the formation of the egg cell, rather than the offspring directly. These genes determine the orientation and organization of the embryo and its tissues. Therefore, they affect the composition and developmental potential of the oocyte.
