If the differences in concordances are high between MZ and DZ twins, this would suggest a higher genetic component because MZ twins share the genome. On the other hand, if there are no differences in concordances between MZ and DZ twins, this could indicate that environmental factors (either in utero or after birth) may contribute to these particular traits.
