Background: The investigation of the genetic components of human physical characteristics and disorders uses twin research. Cotwins who are monozygotic (MZ) share all of their genes, whereas dizygotic twins (DZ) typically only share half of their DNA. Therefore, one can assess the relative contributions of genetic and environmental influence to observed variances in certain features or traits by assuming that both types of twins have been sampled from the gene pool and that equivalent environmental forces have been placed upon them. Numerous oral features including dental caries appear to have a significant hereditary component, according to twin studies.  contribution.
