what are the importance of genetics?

Answer 1

Areas of genetics

Classical genetics

Main articles: Classical genetics, Mendelian inheritance

Classical genetics consists of the techniques and methodologies of genetics that predate the advent of molecular biology. After the discovery of the genetic code and such tools of cloning as restriction enzymes, the avenues of investigation open to geneticists were greatly broadened. Some classical genetic ideas have been supplanted with the mechanistic understanding brought by molecular discoveries, but many remain intact and in use, such as Mendel's laws. Patterns of inheritance still remain a useful tool for the study of genetic diseases.

Behavioral genetics

Main article: Behavioural genetics (British spelling)

Behavioral genetics studies the influence of varying genetics on animal behavior. Behavioral genetics studies the effects of human disorders as well as its causes. Behavioral genetics has yielded some very interesting questions about the evolution of various behaviors, and even some fundamental principles of evolution in general. For example, guppies and meerkats seem to be genetically driven to post a lookout to watch for predators. This lookout stands a significantly slimmer chance of survival than the others, so by the law of survival of the fittest, it would seem that this trait would be lost after a few generations. However, the gene has remained, leading evolutionary philosopher/scientists such as Richard Dawkins to begin making sub-clauses to the rule of survival of the fittest. The interactions and behaviors of gregarious creatures is partially genetic in cause and must therefore be approached by evolutionary theory.

Clinical genetics

Main article: Clinical genetics

Physicians who are trained as Geneticists diagnose, treat, and counsel patients with genetic disorders or syndromes. These doctors are typically trained in a genetics residency and/or fellowship.

Answer 2

Understanding genetics is the key to understanding what makes each living organism so unique and special. Also, I believe that if we understood more about genetics it would be possible to develop cures and treatments for a lot of terrible illnesses.

Answer 3

To understand the path of all life forms on this planet. To understand why we are the way we are.
