Abstract excerpt
The genetic and environmental contributions to determine digital dermatoglyphic traits were investigated by using female dizygotic and monozygotic twin pairs to estimate heritability indexes (h(2)). The evaluated sample was composed by 20 monozygotic twin pairs and 13 dizygotic twin pairs. A significant heritability (h(2) = 0.65 to 0.96) was observed for 12 dermatoglyphic characteristics (delta indexes and ridge...
