Final answer:
If a trait is predominantly due to genetic transmission, it will be seen more frequently in identical twins than in fraternal twins.
Step-by-step explanation:
If a trait is predominantly due to genetic transmission, it will be seen more frequently in identical twins than in fraternal twins. Identical twins originate from a single fertilized egg and share 100% of their genetic material. Fraternal twins, on the other hand, develop from separate fertilized eggs and share only 50% of their genetic material, similar to non-twin siblings. Therefore, if a trait has a strong genetic component, it would be expected to be more prevalent in identical twins than in fraternal twins.
