Hi no i have a different blood type i thing it all goes on your genes. It could be to do with relative and all sorts. But i did read some where once that if both parents have the same coloured eyes then its 100% that the child will have brown even thought any other colour eyes might run in the family. So maybe you should check the eye. As we think my dads dad wasnt his real dad as both my nana and grandad had brown eye and my dad has blue but his older sister has brown. But who knows the only way is through a dna test.

i was once told that when it comes to your blood type there are two parts the letter and the rhesus negative or positive part, i was told that you would get one part from each of your parents ie the letter from your mum and the rhesus part from your dad or vice versa thus making up your blood group dont know how true this is but if it is then it would be strange for two siblings to have two different blood groups a dna test is more accurate xx

As i understand it, you have to have one of your parents' blood groups, so one brother could have mums and one dads. They may of course have different dads, but why delve into that if its only going to cause problems.

No. My daughter has her dads blood type and not mine. And my son has my blood type and not his fathers. But we know for sure that they belong to us .

Not at all. You would have to consider DNA, not blood type, when determining relation.

No! It may be that he has his das's blood group and his bro has his mum's, or vise versa.
