September 1, 2015. It seems like brothers and sisters should have the same ancestry background. After all, they both got half their DNA from mom and half from dad. But because of how DNA is passed on, it is possible for two siblings to have some big differences in their ancestry at the DNA level.
The presence of a given genetic trait in only one member of a pair of identical twins (called discordance) provides a powerful window into environmental effects. The classical twin design compares the similarity of monozygotic (identical) and dizygotic (fraternal) twins. If identical twins are considerably more similar than fraternal twins (which is found for most traits), this implicates that genes play an important role in these traits.
