Dna is organized into 46 chromosomes, which hold the instructions for heredity. Another influence on heredity from conception is the environment. While the womb is highly protected, external factors like the health of the mother can affect the child. Newborns also are influenced heavily by external factors, because they depend on adults for survival.
