[|Human|] Hi I am George!Good day!I am just concern with the information that I learned from my friend.She told me that a person with blood type O should not marry a person with blood type A or vice versa. She said that the probability of having a child with genetic disorder or health defects is really high. Is this really true?
[|AI|]  Hi, After going through the details, it's my opinion that there shouldn't be a problem. When close relations marry, the genetic pool reduces and the mutations increase in number. So, the offspring has a higher risk of congenital abnormalities or health defect syn Chat Doctor. If you are not related, the blood groups should not matter. Among blood groups, if the female is Rh negative and male positive, immune hemolytic disease of newborn may be seen. It can be prevented easily. I do not find any reason to stop you for genetic reasons. Any further queries, happy to help again.
