Evidence that Genes Affect Human Behavior The study of identical twins reared apart is a natural experiment where two individuals with exactly the same genes grow up in different environments. By studying chromosomes and genes, scientists are able to determine the genetic basis for many diseases. Research on the human genome has shown that, on average, the DNA sequences of any two people are 99.9 percent the same. o A genetic result can give more information about your child's health now and in the future.
