What is heredity?

Heredity refers to the process through which traits and characteristics are passed from parents to their offspring through genetic material. This transmission involves DNA, which carries the genetic information that determines various traits, such as physical attributes, behaviors, and predispositions to certain health conditions. Understanding heredity is crucial in fields such as genetics, biology, and even psychology, as it explains how traits are inherited and can influence the development and health of individuals across generations.

The other options describe concepts that do not accurately capture the essence of heredity. Uncontrolled genetic mutation pertains to random changes in the DNA that may not necessarily be inherited. Environmental impact focuses on how external factors affect traits, while random pairing of genetic material highlights the combination of genes but does not specifically address the overarching concept of trait transmission.
