If both of my parents are O+ blood type, does that mean that I am?


Answer by  Anonymous

if your the legitimate child of two type O parents, you can be sure that you will have type O blood. the + or - refers to the Rhesus factor, and is inherited differently so we need more information about the genes of your parents to know for sure.

If both of your parents are blood type O+ then you can at least determine your main blood type without rheumatoid factor. You have type O blood, but because we do not know as to whether your parents are homozygous positive or heterozygous positive for their rh factors then we unfortunately can determine yours.

Type O+ blood is the most common blood type in the world. Type O+ blood can be used universally if blood donation is needed because different strains of blood types can be extracted from it, such as Type A or Type B. Your blood type could be different from your parents.

Probably. Most likely you'd be either O+ or O-. Your parents might have hidden alleles though, which would give you a different blood type. DNA tests will tell you your parents.

Yes, your blood type is always one of your parents, the best way to check so you put your mind at ease is to go to your doctor and have a blood test ran. It is painless and not very expensive. It comes in handy to know in case of an emergency.
