Short Answer
Yes. Twins can have different blood groups, especially if they are fraternal (non-identical) twins.
Detailed Explanation
Fraternal twins develop from two separate eggs and two separate sperm, so they inherit different combinations of genes and may have different blood groups.
Identical twins usually have the same blood group because they develop from a single fertilized egg.
Key Points
- Fraternal twins may have different blood groups.
- Identical twins usually share the same blood group.
- Blood groups are inherited genetically.
- Laboratory testing confirms blood group.
