The correct answer is B. Identical Twins. In the case the intelligence of a person were to be determined by heredity where the children receive some characteristics from their parents through the genes, as presented in the D alternative. The identical twins receive 100% of traits from parents.
b. identical twins
Arthur Jensen (1969) argues that intelligence is generally given and that the environment has only a minimal role in influencing intelligence. Jensen reviewed research on intelligence, which mostly involved comparisons of IQ test scores in identical twins and non-identical twins. Identical twins have a similar genetic makeup. So if intelligence is genetically inherited the IQ scores of identical twins must be more similar to each other than the IQ scores of non-identical twins.
Research shows that the correlation of IQ test scores of a family is around 0.50. while between two twins, the correlation of IQ test scores was very high, around 0.90. other evidence is on adopted children. Their IQs correlate around 0.40 to 0.50 with real fathers and mothers, and only 0.10 to 0.20 with foster fathers and mothers. furthermore, the evidence in twins raised separately, their IQs remain highly correlated, even though they may never have known each other.
Genetically the structure and function of our brain contribute to the level of intelligence. Specific features that might affect intellectual intelligence include the size and shape of the frontal lobe, the amount of blood and chemical activity in the frontal lobe, the amount of gray matter in the brain, the overall thickness of the cortex and the level of glucose metabolism. The pathways that function well correlate to better brain function, efficient processing and brain information processing, all of which show better intellectual intelligence values.
