If heredity is an important determinant of a specific behavior, what prediction can we make about identical twins reared apart compared to fraternal twins reared apart?

If heredity is an important determinant of a specific behavior, what prediction can we make about identical twins reared apart compared to fraternal twins reared apart? Options: (a) Fraternal twins will express the behaviour more similarly than identical twins (b) Little similarity in either set (c) Identical twins will express the behaviour more similarly than fraternal twins (d) Behaviour will be expressed as similarly by identical twins as fraternal twins ✅ Correct option: (c) Identical twins will express the behaviour more similarly than fraternal twins Explanation (200+ words): Heredity significantly affects behavior. Identical twins share 100% of genes, whereas fraternal twins share about 50%. Therefore, traits with strong genetic determinants are expressed more similarly in identical twins, even if reared in different environments. This principle underlies twin studies in psychology to separate nature vs nurture influences. Option (c) accurately reflects this fact. 10 PPSC-Oriented Facts: 1. Identical twins share all genes. 2. Fraternal twins share half genes. 3. Genetic traits appear similarly in identical twins. 4. Twin studies help measure heredity impact. 5. Behavior has genetic and environmental components. 6. Reared apart twins test heredity influence. 7. Nature vs nurture principle. 8. Psychological traits analyzed using twin studies. 9. Intelligence and temperament often studied. 10. Standard PPSC psychology question.
