hereditary definition. A descriptive term for conditions capable of being transmitted from parent to offspring through the genes. The term hereditary is applied to diseases such as hemophilia and characteristics such as the tendency toward baldness that pass from parents to children. Word of the Day.
Heredity is the passing on of traits from parents to their offspring, either through asexual reproduction or sexual reproduction; the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is called genetics, which includes the field of epigenetics.
