Birth Weight

Birth weight is another multifaceted trait influenced by a combination of genetic and environmental factors. While it’s true that a mother’s overall health, nutrition, and prenatal care can significantly impact a baby’s weight at birth, genetics also plays a substantial role in determining birth weight. According to scientific research, a significant portion of a baby’s birth weight is genetically determined by the mother’s genes.

If the mother was a heavier baby herself, there is a greater likelihood that she may give birth to a baby with a higher birth weight. However, it’s essential to recognize that birth weight is not solely determined by genetics, and the interplay of various factors, including maternal health and prenatal care, contributes to the ultimate birth weight of the baby.
