Effects of the chorion type on prosocial behavior in young South Korean twins.

Twin research and human genetics : the official journal of the International Society for Twin Studies - 1 Oct 2007

Hur Yoon-Mi

Abstract excerpt

The present study examined the possible effects of chorionicity of twins on variation of prosocial behavior in the classical twin design. Mothers of 56 pairs of monochorionic monozygotic (MCMZ) twins, 34 pairs of dichorionic monozygotic (DCMZ) twins, and 316 pairs of dizygotic (DZ) twins rated their children's prosocial behavior. The MCMZ correlation for prosocial behavior was similar to the DCMZ correlation (.63...
