Question

which pair would you expect to look more dissimilar?
identical twins
fraternal twins

Explanation:

Identical twins come from a single fertilized egg that splits, so they share nearly 100% of their genes. Fraternal twins come from two separate eggs fertilized by two separate sperm, so they share about 50% of their genes (similar to regular siblings). Since genetic similarity affects physical appearance, fraternal twins are expected to look more dissimilar.

Answer:

Fraternal twins
