One of the studies that has been conducted is titled ″Sources of Human Psychological Differences: The Minnesota Study of Twins Reared Apart.″

Why are twin studies important in biological psychology?

Understanding how and why twin studies are employed is an essential issue in biological psychology.

What did the Minnesota study?

  1. The Minnesota Twins Study focused on monozygotic twins, sometimes known as identical twins, because these individuals shared every single gene that had been passed down to them.
  2. Therefore, the researchers made the assumption that any differences that occurred between identical twins who were raised in different environments were caused by the environment, and that any similarities that occurred between identical twins who were raised in different environments were caused by genetics.

What do twin studies tell us?

Studies on twins make it possible to tease out the common genetic and environmental elements that contribute to a particular characteristic of interest. Researchers are able to make an estimate of the proportion of a trait’s variability that can be attributed to genetic variation, as opposed to the proportion that can be attributed to shared environment or unshared environment.
