Heredity refers to the transmission of physical and psychological traits from parents to their children through genes. It plays a fundamental role in shaping a person’s physical characteristics, such as height, skin color, and eye color, as well as their mental abilities, personality traits, and health conditions.
From the moment of conception, a child inherits 46 chromosomes, 23 from each parent, which contain genes responsible for various traits. These inherited traits set the basic potential and limitations for development.
Heredity influences:
- Physical growth and body structure
- Intelligence and memory capacity
- Temperament and behavior
- Risk of genetic disorders and diseases
While heredity provides the foundation for development, it works closely with the environment to shape the full personality and behavior of a person. Thus, heredity plays a vital but not exclusive role in human development.
