QUESTION:

Researchers are very interested in studying identical twins separated at birth and raised apart. So far, the data reveal that such twins frequently have similar personalities, mannerisms, habits, and interests. What general question do you think researchers hope to answer by studying such twins? Why do identical twins make good subjects for this research? What are the potential pitfalls of this research? What abuses might occur if the studies are not evaluated critically?

ANSWER:


The general question that researchers hope to answer by studying identical twins separated at birth is how much of our behavior is determined by genetics, and how much is influenced by environmental factors. Identical twins make good subjects for this research because they share the same genes and have been raised in different environments, which allows researchers to analyze the effects of genetics and environment separately. Additionally, they provide a large sample size in a small study, so researchers can make sure their results are reliable.
