Twins Separated at Birth

Vote 0 Votes

One important concept from Psychology 1001 text is the study of Nature vs. Nurture. Gregor Medel was the first to suggest heredity. By studying a series of pea plants and how they carried different characteristics through generation to generation. Now we understand that chromosomes are responsible for carrying out this process. Genes are accountable for telling how tall one will be, your hair color, eye color, and personality types; or are they? The age-old question nature vs. nurture comes into play while talking about genetics and heritability, meaning what is one able to inherit from your genes? Nature vs. nurture seeks to find out this question using family studies, twin studies, and adoption studies. Scientists use these three measures to track the presences or absences among certain trait in different relatives. Family studies measure what traits are passed along in families. Twin studies are the easiest to determine because of some sets of twins being dizygotic. Since these sets of twins are identical in genes, one is able to figure out whether genes are passed on through genes, or simply by environmental factors. Adoption studies examine how many traits are passed on using environmental factors. If the adopted child still contains personality genes from their parents and not from their new environments.

This is an important concept to me because it makes me wonder if the way I act is actually genetic or just in part due to whom I have grown up and lived with all my life. Being away at college it makes me wonder if I will adapt to my new environment and change who I am just because I am not around the same people anymore.

Correlation vs. Causation: Does A really cause B? With these twins separated at birth, is the reason they have similar interests in many things due to the fact that they have the same genes or simply just a coincidence?
