There is no way to calculate the heritability of a trait or behavior directly, so scientists must infer it. Explain, in detail, the two approaches that are used for that purpose
What will be an ideal response?
A good answer will include the following key points:
• One way to estimate heritability is to compare adopted children to their biological and adoptive relatives.
? Similarities to their biological relatives are more likely due to genetics.
? Similarities to their adoptive relatives are more likely due to experience and environment.
• Another method is to compare identical twins with same-sex fraternal twins.
? Although there are some exceptions, most identical twins are genetically identical.
? In contrast, fraternal twins only share half of their genes.
? If identical twins are more like each other than fraternal twins, the increased similarity is attributed to genetic influences.
? Researchers have also studied identical twins that are separated shortly after birth and raised in different environments.
