Suppose a researcher finds that taste in music tends to be much more similar for identical twins than it is for fraternal twins. This would suggest that the heritability for musical taste:
A) is relatively high.
B) is relatively low.
C) is higher for identical twins than fraternal twins.
D) is higher for fraternal twins than identical twins.

Question

The fact that taste in music tends to be more similar among identical twins suggests that genetics play a larger role in determining musical taste. This is because identical twins share 100% of their genetic material, while fraternal twins share only about 50%. Therefore, if musical taste is more similar among identical twins, it is likely that genetics are a major contributing factor, leading to a relatively high heritability.
