Yes, twins can be the same gender but look different. If they are fraternal twins, they develop from two separate eggs fertilized by two different sperm cells, resulting in unique genetic combinations. As a result, they can look quite different while still being the same gender. On the other hand, identical twins arise from a single fertilized egg that splits into two, sharing the same genetic material, and generally look very similar.
