Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Indicate your answer using the codes given below :
Assertion (A) : Heritability of intelligence explains variations due to genetics for individuals within a given population.
Reason (R) : Earlier the children from deprived families were adopted, the higher their intelligence score will be.
Codes :
UGC NET - 2013,
Answer: B
Both statements are true, but the Reason does not explain the Assertion.
Heritability is an estimate of how much of the variation among individuals in a population is due to genetic differences. It does not apply to a single person, so the Assertion is accepted. Children adopted early from deprived homes tend to score higher, which is also true.
The adoption finding concerns the effect of environment and does not explain what heritability means, so the Reason is not the explanation.
