Lykken and Tellegen Conducted a Study of Twins That Showed

Lykken and Tellegen conducted a study of twins that showed that even though monozygotic (identical) twins tend to make similar choices in many aspects of their lives, this is not true when it comes to mate selection. The spouses of monozygotic twins are no more similar to each other than are the spouses of dizygotic (fraternal) twins. What important idea can we infer from this study?

A) Mate selection is a dyadic process and, hence, is rather different from other choices that people tend to make.
B) Attraction has a clear biological substrate, but environment also plays a crucial role.
C) Monozygotic twins tend to select different kinds of partners compared to dizygotic twins.
D) Mate selection is heavily shaped by genetic influences.
