How can researchers determine the heritability of a trait?
What will be an ideal response?
A good answer will include the following key points:
• Scientists currently have no way to estimate the heritability of a trait or behavior directly, so they must infer it by studying people whose degree of genetic similarity is known.
• Researchers can compare correlations between the traits of adopted children and those of their biological and adoptive relatives and can use the results to compute an estimate of heritability.
• Another way to estimate heritability is to compare identical twins with same-sex fraternal twins.
• The assumption is that if identical twins are more alike than fraternal twins, then the increased similarity must be due to genetic influences.
