Heredity is the mechanism by which all traits are inherited by offspring from his/ her parents. To transfer these traits, some medium is required; it is nothing but through the genes contained in the chromosomes. It is because of heredity, we find a similarity between the children and their parents.
Types of Heredity
- Includes language, customs, traditions, taboos. We can broadly classify heredity into two major groups, Biological Heredity, and Social Heredity.
-
Biological heredity includes the colour of skin and eyes, intellectual ability, shape of the nose, hair pattern, etc. These are some examples of traits acquired biologically.
- The hereditary traits can also classified be into two categories, physical traits, and mental traits.
-
Physical traits include the traits responsible for our physical appearance, this may include eye colour, blood type, skin colour, height, etc.
-
Mental traits govern the mental make-up of an individual. Intelligence and musical ability are some of the examples of mental traits.
Thus from the above-mentioned points, it is clear that the colour of the eyes is predominantly a heredity related factor.
