Twin Studies Provide Insight into Nature vs. Nurture

Twins, both (11) **identical** and fraternal, provide scientists with a unique opportunity to study the relationship between genes and environment. Identical twins are particularly interesting because they share the exact same (12) **DNA**, whereas (13) **fraternal** twins do not.

Researchers have discovered that both genes and (14) **environmental** experiences play a role in shaping our (15) **behavior**. If genes alone determined everything about us, identical twins would be (16) **identical** in every way. However, this is not the case - identical twins often have different interests and personalities.

By studying the similarities and differences between twins, scientists can begin to determine which of our qualities are passed down from our (17) **parents** and which ones result from our life experiences. This can help shed light on the long-standing debate over the relative importance of (18) **nature** and (19) **nurture** in human development.

Ultimately, twin studies give researchers a valuable tool for unraveling the complex interplay between our (20) **genetic** makeup and the environments in which we grow up.
