When studying jibe there are resembling gibe, fraternal twins, and modern twin studies. Identical twins have identical genetic compositions, therefore; studying identical twins that were raised in different environments helps scientist see the continue of genes and how they develop. Scientists can study fraternal twins who were raised in the same environment to determine the impact of the outside environment and the development of a twins personality. Fraternal twins only dowery 50 percent of their genes. Modern twin studies have shown that almost all of a persons traits are influenced. They share very little genes in commen.
