Document Summary
Half of our genetic code comes from each parent they each give us half of their genetic code but we get a random selection. Thus, our genetic code will be different (based on random selection) from the genetic code of our siblings. On average, we share 50% of our genetic material with our siblings. Determine the percentage of individual differences in a trait that can be attributed to genetic differences and the percentage that can be attributed to environmental differences. Determine the ways in which genes and environment interact and correlate with each other to produce individual differences. Proportion of observed variance in group of individuals that can be explained or accounted for by genetic variance. Environmentality = proportion of observed variance in group of individuals attributable to environmental variance. Finding that a personality trait has a genetic component does not mean the environment is powerless to modify trait. Selective breeding - studies of humans" best friend.
