Definition


Heredity is the passing on of genetic characteristics of one species through the generations. An individual's genetic information is contained in their gene cells. When an egg is fertilized, a spermatozoa comes into contact with an ovum, each containing all the genetic characteristics of the man and woman, combining to create a new individual who will possess the hereditary characteristics of his or her parents, such as hair color, facial shape, or even diseases.
