Why do sociologists need to be careful when drawing conclusions from twin studies?
the results do not apply to singletons.
the twins were often raised in different ways.
the twins may turn out to actually be fraternal.
the sample sizes are often small.

The correct answer is "The sample sizes are often small". Socialization is not only important because it helps uphold societies and cultures, but also because it is a key part of individual development. Sociology is more interested in the way that society's influence affects our behavior patterns.
