biological parents

Biological parents are the individuals who contribute their genetic material—sperm from the father and eggs from the mother—to create a child. They are the genetic source of a child's traits, such as eye color, blood type, and inherited health factors. Biological parentage is determined through genetic links, though social and legal definitions of parenthood may differ. In essence, biological parents are the person's genetic origin, providing the biological foundation for their physical and hereditary characteristics.
