RH(D) O positive blood my husband is O my daughter was born with A+

Blood type only comes from the parents of the child…therefore for her to have A+ then you are either mistaken about one of your blood types or your husband is not her father. She can not get a blood type from anyone else in your family…just her mom and dad.

This must be possible in some way as I have been trying to find out exactly the same thing. I am O du and my husband is O+ yet my second daughter is A+. There is absolutely no possibility of ‘funny business’ either. Her father is definitely her father and I am her mother, she wasn’t swapped as a baby by mistake, so all I can assume is the blood tests are not sensitive enough at the moment. After all my blood type has been changed since they have more sensitive tests nowadays…Couldn’t really answer but at least your not alone:)

possibly someone else in your family.. maybe even an ancestor. you’re family traits may not show for even hundreds, thousands or millions of years!! but they can still be passed down.. someone in your family probably has A+ type.

given that O is a recessive gene and needs both Os to express itself… that isnt actually possible… either your husband isnt the father, or one of you is mistaken about your blood types… or my memory of blood types is wrong… although this site does seem to agree with me…

talk to your doctor…

it is true that two os make an o. you have to be mistaken about someones blood type.
