Question

yining cheng · Accepted Answer

Final Answer : C, Explanation :  Dr. Cardinale is studying the effects of heredity and environment on intelligence, which falls under the realm of behavior genetics. Comparing the IQ scores of identical twins (who share 100% of their genetic makeup) to fraternal twins (who share approximately 50% of their genetic makeup) can help her determine to what extent genetics influences IQ. Human genome and molecular genetics focus more on the study of specific genes and their effects, while selective breeding is a term used in animal breeding, not relevant to this scenario.
