Operational definition of similarities in twin studies points out an individual's mental aptitudes. These studies also compare criminal behavior between homozygotic twins.
In the creation story of the Iroquois people, the left-handed twin represents chaos and destruction, while the right-handed twin represents order and harmony. The people sing and dance for the left-handed twin as a way to pacify and appease his chaotic nature, hoping to prevent his destructive actions and maintain balance in the world.

The average time between twin births is around 10-15 minutes. However, it can vary widely depending on individual factors such as the position of the babies and the mother's health.

There used to be a theory that another, twin Earth could be orbitting the sun, exactly opposite from us and therefore always invisible. In fact because the Earth's orbit is an ellipse, its impossible for a body to orbit the sun and always be invisible. For now, astronomers and scientists think Venus is Earth's twin.
The four methods of study in behavioral genetics are family studies, twin studies, adoption studies, and molecular genetic studies. Family studies look at the occurrence of traits within families, while twin studies compare the similarities between identical and fraternal twins. Adoption studies examine the influence of genetics and environment by comparing adopted individuals with their biological and adoptive families. Molecular genetic studies analyze specific genes and their impact on behavior.
Twin studies are also referred to as twin research or twin analysis, as they involve comparing characteristics of twins to understand the influence of genes and environment on traits or behaviors.
Some people criticize twin studies because they assume that twins growing up in the same environment experience similar influences, which might not always be the case. Additionally, critics argue that twin studies may not account for genetic differences within twin pairs or the potential effects of epigenetics. Lastly, some critics suggest that the results of twin studies can be influenced by researcher bias or methodological limitations.

It has no effect at all in a basic sense. Some studies have found that one twin tends to express half the traits of the chart and the other twin the remaining half.
No. Linkage studies use markers to identify chromosomal regions that may be linked to disease. Twin and adoption studies establish heritability and thus the genetic basis of a disease, not which chromosome or chromosomal region may be implicated. For this reason they are called genetic epidemiological studies.
