Answer:
The Meaning of Heredity:
Man’s behaviour is influenced by two forces: heredity and environment. The biological or psychological characteristics which are transmitted by the parents to their off-springs are known by the name of heredity. Heredity is, in other words, a biological process of transmission of certain traits of behaviour of the parents to their children, by means of the fertilized egg. Heredity traits are innate; they are present at birth.
The human individual is the progeny of two parent cells that come together when a male sperm fertilizes a female egg. In the nuclei of these parent cells are certain hair like substances called ‘chromosomes’. The chromosomes contain chemical substances called genes. These basic substances, chromosomes and genes determine characteristics of the individual. And this is what constitutes heredity.
