My blood type is o+ and my x-wifes blood type is o+, my childs type is A- is there a chance she is not mine.?

Answer 1

According to the information given, it is not possible for the A negative child to be your child. Bummer. Sorry. You better re-test to make sure though.

If both parents are type O, their children must be type O as well.

Answer 2

Get another blood test before you jump into any hasty conclusions :) But it does sort of indicate that your child might not be your child.

In general, someone who has blood type A must either have AA or AO genotype. However, you said your ex-wife's blood type is O, so therefore your child must be AO [your ex-wife contributed to the O because there was no way she could contribute to an A. She doesn't have the A allele.]

The "A" must have come from somewhere, and if both your ex-wife and you are O blood types, where your genotypes are OO... something fishy might be up.

Answer 3

Sorry to break the news to you Kevin, but I've got to back up Carrina.
Everybody has 2 blood type alleles, combinations of AB&O.
Type O is recessive. So for you to have an O genotype, you must be OO. Same for your ex.
The child's A genotype will be from AO alleles. The A allele very likely came from somebody other than you. But to know for sure, you will need to pay for a paternity test.

Though the chances are rather high the child's genes are not from you, the fact remains that you have raised her and love her. Would she be any less your child or less loved had you adopted her?
If you feel anything different from the knowledge, direct your reaction to your ex. Just chalk it up on list with other reasons she is your ex.
Might it be better to skip the paternity test and dis the thoughts that your daughter is any less a product of you? In time, she will grow and become her own woman. Where her genes came from will have no relevance to your pride in her.

Answer 4

I would trust a paternity test and not a blood test.
Generaly you are OO and your wife is OO and there is no "A" to pass on to your daughter. Normally two people who have type O blood (whether it is positive or negative) can only have type O children. However, there is a rare condition where this is not true. I'm not sure what it is called, it has been so long since I learned about it, but it can cause a family obvious greif.

Answer 5

Without jumping to conclusions, if there is any doubt ... get a paternity test.

Anyone's child might not be their own in a society where so much cheating goes on. A paternity test will put your mind at ease, one way or the other. Since you already have doubts, it's best to know once and for all.

Good Luck!

Answer 6

e_lunar35 is wrong, if your wife's blood type is AO she will be A, NOT O since O is a recessive blood type and to have O type blood you can only be OO

Answer 7

Well i think get the test done again to confirm as some times Labs give wrong results . but i would advise u dont go into such details now as u have grown up that child, n she calls u papa , just think of it, it doent matter much now whome she belongs, u must have a strong band of love with her , just flourish it n take care of the kid. dont get yourself confused by going into such details now All the best :)

Answer 8

Jeff is definitely no longer the daddy. consequently, the a danger blood communities of youngsters are A, B and AB yet in no way, in spite of everything O. No danger. So, he's precise, the toddler isn't his.

Answer 9

Best go with DNA to be sure. Blood types alone can be deceiving.

Answer 10

NO TO O- BLOOD TYPES ARE A RARE POSSIBILITY BUT THE CHILD COULD ALWAYS HAVE A DIFFERENT BLOOD TYPE THEN THE PARENTS. GOD MADE US THAT WAY
