Correct Answer - Option 2 : a combination of heredity and environment
Development refers to an increase in structure for better and enhanced functioning of organs. It is a product of the interaction of hereditary and environment.
- Development takes place when environmental forces interact with the hereditary forces in an organism as they are the elements that play a vital role in determining the development of an individual.
-
How a person will develop depends on the environment but how far a person can develop depends on heredity.
- Heredity places limit on IQ and the environment determines the numeric position of IQ within these limits.
Let's Understand in Brief:

Heredity Factors |
- Heredity refers to the genetic constitution of an individual which is established during conception.
- It is the property of organic beings by which offspring have the nature and characteristics of parents or ancestors.
- Hereditary influences have a bearing on the traits likely to exist in a child. It is because of this that members of a family bear a physical resemblance to each other and a high degree of correlation exists among siblings than others.
- To stimulate the hereditary potential, the environmental stimulation must be of the right kind at the time when development normally occurs.
|
| Environmental Factors |
- Though heredity and environment are closely inter-related and each human being at birth has a gene determined physical, mental and biochemical potential.
- This potential may not be reached because of environmental influences. Stimulation to the development of innate abilities comes from the environment.
-
Environment influences this potential only to a limited extent favorably or unfavorably.
- Therefore, inborn capacities must be stimulated by environmental factors. Good seeds planted in poor soil result in stunted growth.

Thus, from the above-mentioned points, it is clear that a child's development is the result of a combination of heredity and environment.
