Answer 1

Answer & Explanation:

'Identical twins separated at birth & raised apart' make an interesting subject for research :

• Gives insights into personality variation among twins, despite of having the same DNA
• Idea about 'Nature vs Nurture', to study how birth & environmental factors shape the cognitive & behavioural aspects of twins
• Analysis of heritability of traits, & factors affecting individual differences in ageing
