What is heredity?

Heredity refers to the biological process through which genetic information is transmitted from parents to their offspring. This encompasses the passing down of genetic traits, such as physical characteristics (like eye color or height) as well as predispositions to certain diseases and conditions. Understanding heredity is fundamental in the study of child growth and development, as it directly influences various aspects of a child's physical, emotional, and intellectual development.

The other options describe different concepts related to child development. Environmental factors (the first option) relate to the surroundings that can impact growth and development, such as family structure, socioeconomic status, and community resources. The third option focuses on learned behaviors, which are shaped through social interactions and experiences, rather than biological inheritance. The fourth option addresses nutritional needs, which are crucial for proper growth and health but do not address the genetic transmission of traits. Therefore, the correct answer emphasizes the genetic aspect of development, which is central to understanding heredity.
