Twins hold a special place in science as a source of insight into human behavior and genetic links. Fraternal and identical twins and multiples of all ages are invited to join the Registry for consideration for research studies.
Twins & Families
Registry members participate in Twin studies conducted on identical or fraternal twins. They aim to reveal the importance of environmental and genetic influences for traits, phenotypes, and disorders. Twin research is considered a key tool in behavioral genetics and in content fields, from biology to psychology.
Clinical Trials
Identical and fraternal twins participated in a study to better understand the genetic components of the body’s immune response to the flu vaccine.
