Describe three ways in which researchers have used twins and children who have been adopted to study the contribution of genes to particular behaviors.
What will be an ideal response?
Ans: Scientists have been able to look at concordance rates between identical twins and between fraternal twins to try to identify which behaviors or personality traits are linked with genetic inheritance. If identical twins, who share almost all their genes, are more similar to each other (that is, they have a higher concordance rate) on a trait such as shyness than fraternal twins, who share only half of their genes, the researchers conclude that genes play a role in determining whether someone is shy. Research with twins has also examined the role of specific aspects of the environment rather than looking only at the effects of similarity in genes. If identical twins who are raised in different homes are more similar to each other on a certain characteristic than fraternal twins who are raised together in the same home, it suggests that genes are the stronger influence on the characteristic being studied.
