Heritability
When a child is born, he or she is born with the genetic endowment of their parents and parental family. There are certain traits that a child have innately or that is by birth, these are called the heritable trait. The study of genetics or gene mapping helps us to understand the contribution of certain gene and how they are influencing the phenotype of a person. These traits determine the behaviour and personality along with the acquired traits or personality that is the ones that the child learn through their experiences. Heritability might refer to anything that can be inherited. Which might not only restrict to the genetic contribution. When a person is born in a family, the person might inherit many worldly or monetary belongings of the family. Heritability ensures the familial continuity of gene pool as well as security of familial wealth which is both quite important.
