They tested female twin pairs (136 monozygotic, MZ, and 148 dizygotic, DZ) for pitch recognition ability, and applied genetic model-fitting techniques to ascertain the genetic and environmental ...

A form of experimental design in which investigators examine twins (both monozygotic and dizygotic) who were reared together or apart in order to determine the relative contributions of genetics ...

The research surveyed more than 1,500 parents of monozygotic and dizygotic twins aged 3 to 9. It found that when one twin was typically developing and the other had a developmental condition ...

Linkage in 181 dizygotic twin pairs yielded a 6.93 lod score. The PPARG C→T substitution allele was far less common in monozygotic twins than in dizygotic twins. Dizygotic heterozygosity was ...
