The BASICS on TWIN STUDIES:)

Twin studies are very common studies scientists like to elaborate due to their wide variety of benefits and information. Twin studies are important for genetic and psychological research. Twins are so easy to analyze and examine because they provide a natural control for experiments. Even though twins are a very common scientific topic this experiments can become very controversial due to the fact that for a scientist it is very easy to damage the twin’s feelings or privacy. Several twin studies are considered unethical.

Twin studies are usually processed to study genetics, embryological, biochemical, immunological, behavioral and sociological aspects. All of these topics can be covered with a twin study due to these variety of topics associated to this studies, twin studies have become very useful and popular for scientist. The basic logic of how twins studies or research can be understood with very little mathematics and the concept of variance. The classic twin study begins by assessing the variance of behavior in a large group, then scientist analyze three main components which are: how much of this is due to genetic (heredity), how much appears to be affected by environmental effects, and events that affect each twin differently. All of these questions are identified scientifically by component A (additive genetics), C (common environment), and E (unique environment). When the ACE is all analyzed and processed scientist and researchers can determine the proportion of variance in traits between the twins.
