Answer 2

Genetics is the science which deals with the study of and variation​ of genes and heredity.

Heredity refers to what is inherited from the previous generations. These inherited traits can manifest themselves both as physical and mental aspects. Genes are responsible for what is inherited. Genes are extremely tiny structures made of proteins that contain the information on how we are, and genetics is the study of genes. What makes individuals unique is the fact that they have a mix of genes from both the parents. This gives rise to the possibility of numerous combinations that can define the personality of an individual. Heredity is extremely important, especially in diagnosing and treating chronic illnesses.
