The "Maternal Effect" refers to the influence a mother has on the traits and development of her offspring, primarily through the provision of resources and environmental factors during gestation or early life. This effect can include the transfer of nutrients, hormones, and even specific genes that shape the offspring's characteristics. In many species, including humans and animals, maternal behaviors such as nurturing, feeding, and protection play a crucial role in the survival and health of the young. The maternal effect can significantly impact growth, behavior, and overall fitness, highlighting the importance of maternal care in the life cycle of organisms.
