Question

Examlex · Accepted Answer

The Answer is Twin Study:
In a twin study, the National Association of Music Teachers could compare the musical abilities of identical twins (who share 100% of their genetic material) with fraternal twins (who share 50% of their genetic material). If musical ability is found to be more similar in identical twins than in fraternal twins, this would suggest a strong genetic influence on musical ability. On the other hand, if musical ability is found to be similar in both types of twins, this would suggest a stronger environmental influence.

Adoption Study:
In an adoption study, the association could compare the musical abilities of adopted children with those of their biological parents and their adoptive parents. If the musical abilities of adopted children are more similar to their biological parents than their adoptive parents, this would suggest a strong genetic influence. Conversely, if the musical abilities of adopted children are more similar to their adoptive parents, this would suggest a stronger environmental influence.

Results:
If the results of both studies consistently show that musical ability is more similar in individuals who share genetic material, this would lead to the conclusion that musical ability is influenced to a large degree by genetic factors. Conversely, if the results consistently show that musical ability is more similar in individuals who share environmental factors, this would lead to the conclusion that musical ability is influenced to a large degree by environmental factors.
