Meaning of Heredity
‘Heredity’ is a word that has been derived from the Latin word ‘Hereditas’ which is referred to the traits which have been inherited by the children from their parents.
Heredity is a term that denotes the process through which mental and physical characteristics are being transmitted to the children from their parents at the time of their conception. In particular, children inherit all the ancestral traits which were passed on by their parents through the reproduction process which is known as heredity.
The traits that came from heredity cannot be changed if these traits have been acquired by the children from their parents or ancestors. These traits have always remained present in the person through life since the conception period.
In particular, heredity denotes that a beautiful couple will produce beautiful children and the same goes with the IQ level of their parents passed on to their children. The explanation of the meaning of heredity has been divided into two approaches:
Through this approach, one can understand heredity as the process which brings the mental and behavioral traits of a parent to the child rather than just physical traits. For example, the intellect level, IQ level, temperament, compassion, tidiness, and many more. It is the ‘sum total of inborn individual traits’.
This concept denotes that a child gets the physical features such as skin color, shape, size, strength, hair, and eyes color from the parents.
