There is a constant interplay between these two factors. So far as social traits are concerned, environment exerts a more powerful influence than heredity.
The studies have generally been conducted by psychologists believing in the efficacy of heredity. But it would be wrong to suppose that heredity is responsible for all similarities, and that environment is responsible for all differences.
But if the complex mechanism of heredity is kept into view, it will be clearly realised that the environment alone does not explain all differences. A better name for it is segregation. Conversely, Bengalese families who made Bihar, Uttar Pradesh or Delhi their permanent habitat, generations ago, identified themselves with the people of those states, adopted their language, dress and food habits.
Females have a pair of X chromosomes, while males have X and Y. Two children in the same home do not necessarily have the same effective environment, and the more children differ from each other, the greater difference there is in their effective environments.HEREDITY AND ENVIRONMENT The nature versus nurture controversy— that is, how much of our behavior is due to inherited factors and how much to environmental factors Heredity is the passing of traits to offspring (from its parent or ancestors).
Essay on Heredity | Psychology.
There exists, however, an internal environment, which, at the earlier stages of development, is more influential than the external environment.
It has been found that the hereditary dispositions can do this work only by guiding the course of development along one rather than another line, while the.
Free Essay: Q. Effect of heredity and environment on the development of personality. Ans. What is Personality? Personality can be defined as a dynamic and. Heredity-Environment correlations can be shown in three ways.
