Twin studies allow researchers to examine the overall role of genes in the development of a trait or disorder. Comparisons between monozygotic (MZ or identical) twins and dizygotic (DZ or fraternal) twins are conducted to evaluate the degree of genetic and environmental influence on a specific trait.

Are identical twins genetically the same?

Because identical twins develop from a single fertilized egg, they have the same genome. So any differences between twins are due to their environments, not genetics. Recent studies have shown that many environmentally induced differences are reflected in the epigenome.

What does DZ twins mean?

Monozygotic twin pairs, or MZ twins, are the identical twins. They share 100% genetic similarity as they split from one embryo, where a single egg is fertilized by a single sperm. Dizygotic twin pairs, or DZ twin pairs, are non-identical twins.

Twins are a valuable source for observation because they allow the study of environmental influence and varying genetic makeup: "identical" or monozygotic (MZ) twins share nearly 100% of their genes, which means that most differences between the twins (such as height, susceptibility to boredom, intelligence, depression ...
