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 ...

Fraternal Twins: They are also known as dizygotic twins. They come from two separate eggs, fertilized by two different sperm. They also share about 50% of their genetic material, and have unique ...

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 ...

Consequently, as a preliminary investigation of our hypothesis, we studied dizygotic twins (who are genetically distinct yet share the same uterine environment) with at least one of the pair ...
