Development & Its Relationship with Learning • Topic 3 of 5

Heredity & Environment

The nature-versus-nurture debate is a CTET favourite, and the safe, correct answer is almost always that the two interact — development is the product of both, not one alone. Heredity (nature) is the sum of traits a child inherits through genes from the parents at the moment of conception: eye and skin colour, body build, and the inborn potential for intelligence, height and certain temperaments. Heredity sets the limits or the potential a child is born with. Environment (nurture) is everything that surrounds and acts on the child after conception — nutrition, family, schooling, language, culture, peers and experiences. Environment decides how much of that inherited potential is actually realised. A useful idea CTET sometimes touches is the range of reaction: heredity fixes a range of possible outcomes for a trait, and the environment determines where, within that range, the child ends up. The exam-safe conclusion: neither acts in isolation; heredity provides the raw material, the environment shapes the final product.

✅ Solved examples

1. A child inherits eye colour and basic body build from her parents at conception. These are determined mainly by:
Heredity (nature) — traits transmitted through genes at conception.
2. Two children with similar inherited potential differ greatly in achievement because one had better nutrition, schooling and stimulation. This difference is due to:
Environment (nurture) — the surroundings and experiences that determine how much inherited potential is realised.
3. The most accepted view in modern developmental psychology about heredity and environment is that:
They interact — development is the joint product of both; neither operates alone. Heredity sets the potential, environment shapes its expression.
4. The idea that heredity sets a range of possible outcomes for a trait and environment decides the final point within that range is called:
The range of reaction — it captures how nature fixes limits while nurture fixes the actual outcome inside them.

✏️ Practice — try these, take hints as needed
