The Impact of Variation in Twin Relatedness on Estimates of Heritability and Environmental Influences.

Behavior genetics - 1 Jan 2018

Liu Chang, Molenaar Peter C M, Neiderhiser Jenae M

Abstract excerpt

By taking advantage of the natural variation in genetic relatedness among identical (monozygotic: MZ) and fraternal (dizygotic: DZ) twins, twin studies are able to estimate genetic and environmental contributions to complex human behaviors. Recently concerns have been raised about the accuracy of twin studies in light of findings of genetic and epigenetic changes in twins. One of the concerns raised is that MZ...
