Genetic and environmental mediation between measures of personality and family environment in twins reared together. Behavior Genetics, 39, 24 35. WebThe similar rate between MZ twins reared apart was approximately 76%. DZ twins raised together had a rate of 55%. MZ twins raised apart still had a higher concordance rate than fraternal twins raised together. C: Bouchard et al. determined a heritability estimate of 70% - that is, that 70% of intelligence can be attributed to genetic inheritance. WebSince identical twins often have similar environments, this information by itself does not distinguish between the effects of heredity and environment. When pairs of like-sexed fraternal twins reared together are studied, however, the degree of concordance for schizophrenia is very much lower--only about 15 percent (Figure 17). golden heights church of christ live
