Genetics has a great influence on many aspects in human development. Not only does it influence your health and what you may have inherited in immunities, or health maladies, it can be a great influence on development in skills, such as musical ability, singing, playing instruments, and creativeness in the arts. It can influence whether a person is better in math skills or English skills and writing. Genetics has influences, but does not put in concrete how a person will turn out in their lives. Each person is responsible for that.
