Compare the twin method with the adoption method for the purpose of assessing the contribution of genes versus environment
What will be an ideal response?
Answer: The twin method identifies identical and fraternal twins and assesses the degree of similarity (concordance) between the pairs. Identical twins share 100 percent of their genes, whereas fraternal twins share 50 percent of their genes. A genetic contribution would be indicated were identical twins to show a greater concordance rate for a trait than do fraternal twins. In the adoption method, a specific trait is considered in children who were adopted early in life, with the frequency of that trait in their biological parents (genetic contribution) compared with the frequency in their adopted parents (environmental contribution).
