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 fraternal twins than identical twins.
D) is higher for identical twins than fraternal twins.

Question

The greater similarity in musical taste among identical twins compared to fraternal twins suggests that genetic factors play a significant role in determining musical taste, indicating high heritability. Identical twins share more genetic material than fraternal twins, so greater similarity in traits suggests a genetic influence.
