Parental DNA refers to the genetic material or DNA that is inherited from one's biological parents. Synonyms for this term include maternal DNA, paternal DNA, genetic material from parents, and hereditary traits passed down from one's parents. These terms are often used in fields such as genetics, genealogy, and forensic science in order to identify or trace familial relationships. While parental DNA plays a significant role in determining an individual's physical characteristics, such as eye color or height, it is important to remember that environmental factors also play a significant role in shaping one's development and behavior.
