Analysis Of Codes Of Life: Behavior Genetics

Identical twins are many times seen as genetic reproductions representing variations from twin to the other twin and are created because of environmental factors (Cervone & Pervin, 2010). Since identical twins share identical genetics, his or her personality seems to also share similarities. Moreover, the environment can impact fraternal twins, resulting in fraternal twins personalities and his or her characteristics similar to each other. For example, identical twins. Some research shows twins that are raised in the same residence have little differences from those who are raised in a different home.

Dr. Robert Best’s lecture here at Winthrop was on the topic of genetics. The question at hand was, “Can your parent’s behavioral characteristics be passed down through genetics?” Genetics are essentially the blueprints to each and every one of us. Our characteristics are coded by our genes, however, do genes affect every aspect of us? When looking at the common book, The Glass Castle, it seems apparent that certain traits like intelligence and creativity can be passed through genes, but not necessarily affect behavior and personality.

After meeting they both discovered that both suffer from tension headaches. They both showed high blood pressure and a history of migranes , again this isnt just coincidence.[2] Studies like this are important to psychology to help the nature/nurture debate , as it allows psychologists to show the similarites within the twins even though they are raised in different environments. It also allows psychologists to show why certain differences and similarites occur within the twins. Conclusion After looking through sources and case studies I believe that some behaviour is due to genetics its hard to say whether it is nature or nurture because it is both.

Human behavior is a loosely defined foundation for individuality, generally considered to be influenced and developed by the environment. However, recent molecular studies have exposed genetic factors that suggest a more biological origin for behavior. Gene segments in the genome of humans and other animals have been identified and associated with particular behavioral traits. Is it possible that the presence or absence of even a single gene may predispose one to alcoholism, increased irritability, or enhanced intelligence? Clearly exploration of the nature versus nurture argument with regard to genetic predisposition has social, political, and legal significance.

Obviously genes influence ones behavior in the sense they dictate the limits on what is possible. Heredity contributes many individual differences in temperament and personality, especially differences in emotionality, activity

If identical twins were truly identical, then their development in two different environments would not affect their behavioral differences. Identical twins that are not separated may still differ from each other. Dr. Farber conducted a study that measured the degree of being separated and I.Q. test scores. On average, Dr. Farber discovered that the more separated the twins were, the greater the difference between their I.Q. scores. If intelligence had been hereditary, then these identical twins that were reared apart and separated would still have the same amount of intelligence; yet, they do not (Gruber).

It has been argued that if genes influence behaviour and character, and we cannot choose our genes, then our behaviour is outside our control and we are not responsible. However, we take the view that genes are not deterministic, and that there is scope for an

The world of Genetics is one that is both fascinating and interesting. When tackling how genetics plays a role in behavior, one must look within the scope of what genetics is before dealing with how it plays a significant role in one’s behavior. Simply put, genetics is the study of genes. It is a biological component within the entire study of biology itself. Scientists who study genetics and perform research do so with the intent to learn more about how genetics affects the overall attitudes, behaviors and dispositions of individuals. It could be said that genetics is somewhat of a psychological-biological science as researchers look at the underlying patterns within the genes that cause

Many children are raised by parents who make bad decisions but not all of those children grow up to make the same mistakes. Obviously our overall physical appearance is something decided before birth, by nature. That is something environment will never have any effect on. Our personality however, can be shaped by the people we meet, situations we find ourselves in, how we are raised, and many other varying factors.

“Explain how genetic inheritance may influence one- behaviour, with reference to one relevant research study. “

Is behavior learned? It is inborn? What of aggression, intelligence, and madness? There is a crucial relationship between the behavior of humans toward their own kind and the view of life they hold. Interest in behavioral genetics depends on wanting to know why people differ. According to Jack R. Vale, in Genes, Environment, and Behavior, recognition of the importance of hereditary influence on behavior represents one of the most dramatic changes in the social and behavioral sciences during the past two decades. A shift began toward the more balanced contemporary view that recognizes genetic as well as environmental influences on behavior. Behavioral genetics lies in its theory and methods, which consider both genetic and

Identical twins may share the same DNA make up and grow up in the same household, yet they have very distinct personalities. On the other hand, twins that may have been separated at birth, find that years later when they meet up for the first time that they have very similar character traits and experiences. Researchers have been trying to figure out for years if DNA or environment has a bigger factor in determining a twin’s personality. When researchers try to determine how personalities are developed, they often look to twin studies to determine if DNA or life experiences are influential in personality development.

Human character and behaviour are not only shaped by the genes that encompass the individual’s genotype. Human character comprising mainly of personality, sexuality, morality and intelligence are the products of genetic determinism as well as external environmental factors. “Single genes can have surprisingly strong influences on particular aspects of behaviour.” (Frank., 2009)

The classic debated topic of Nature versus Nurture has been and will always be a quarrelsome subject in the scientific world. Meaning, the issue of the level to which environment and heredity sway behavior and development in a person. Nature can be defined as, behaviors due to heredity. This means the behaviors is based on the inherited makeup of an individual and is an influence of the growth and development of that individuals’ all through life. On the other hand nurture is causes of behaviors that are environmental. This Intel’s the influence is from the individual’s parents, siblings, family, friends and all other experiences that individual exposed to during life. However, these concept of ideas supports the inborn genetic framework,

Another study that has been done was with separated twins. Each twin was raised in a completely different environment than the other. Genetically, they were both identical in every way, but the environment that they were raised in was very different. One twin was raised in a very hostile setting and slowly became violent as an adult while the other twin was
