The importance of genes for the development of behavioural traits is most obvious in cases of twins that are
A) Similar ages as other family members

Question

Quizplus · Accepted Answer

Twins that are reared apart allow for the examination of the influence of genes on behavioural traits while controlling for environmental factors. Twins that are reared together may share similar environmental factors, which could make it difficult to determine the degree to which genes or environment are responsible for any observed behavioural traits. Therefore, option C is the best choice as it provides a clearer understanding of the influence of genes on behavioural traits.
