Given that we know about the effects of genes and the environment, which of the following pairs of children would be expected to be most similar in terms of overall personality, psychological disorders, and intelligence?1. Monozygotic twins, one raised in a wealthy family living in a modern city and the other raised in poverty in a developing nation2. Adopted children from different biological families raised in the same home3. Biological siblings raised in the same house4. Biological siblings, each adopted immediately after birth, one raised in Chicago and the other raised in New York City

Option 3 - biological siblings raised in the same house: they share the same parents (genetics) and were raised in the same house (environment). This is the correct option.

Option 1 - monozygotic twins with entirely different homes: they share the exact same DNA (genetics) but their lives are completely different (environment). The twin living the wealthy family has probably had better nutrition and learning opportunities than the twin raised in poverty.

Option 2 - adopted children from different biological families but raised by the same parents: they share the environment but their genetics are completely different.

Option 4 - biological siblings living in different states with different families: they share some genetics but their experiences differ because of their raising.
