Ans. Behavior genetics is essential to learn and understand. The study of behavioral genetics helps to evaluate the abilities and disabilities of one’s genes and understand the present status by considering the past data. It is also helpful to identify the unique qualities of a particular gene and how they are distributed to further generations. It also focuses on all kinds of behavioral traits and how they get influenced by environmental factors, genetic factors, etc. Different methods explain different new things about an individual's behavior. For example, the twin method and adoption method are two other aspects from which the individual can understand how the parent would change the child's behavior. The twins of similar genes can behave differently in different situations.
