My husband and I are O+ what might our child's blood type be?

Answer 1

absolutely 100% sure it will O+. To be the blood type "O", you must have two recessive genes for O blood type...so your type would be "oo" as would your husbands. Any combination of that will result in "oo" making all your babies O blood type. And since the Rhesus factor (the positive part) is positive dominant, any children you have regardless of the father will result in a baby with a positive blood type.

Answer 2

The last paragraph says it all.
But I thought you might enjoy reading about how it works.

First, let's look at the ABO blood types. Each person receives an A, B, or O gene from each parent. In this system, the A and B genes are co-dominant and the O gene is recessive. Thus, a person whose genetic type is either AA or AO will have blood type A, those with genetic type BB or BO will have blood type B, and only those genetic type OO will have blood type O. This means that a child with type O blood could have parents with type A, type B, or type O blood (but not with type AB). Conversely, if two parents both have type O blood, all their children will have type O blood.

Another medically important blood type is described in the Rh system. These genes were first discovered in the rhesus monkey, hence the designation Rh. The Rh system is actually far more complex than the ABO system in that there are 35 different possibilities that one could inherit from each parent. These, however, are roughly grouped into positive and negative types. In this system the positive are dominant over the negative. If your genetic type is ++ or +-, your blood type will be Rh positive. Only if your genetic type is -- will you be Rh negative. This means that if both parents have Rh+ blood with the +- genes, they could have children who are ++, +-, or --. In other words, their children could be either Rh positive or Rh negative. Children who are Rh negative can have parents who are either Rh positive or Rh negative.

Two parents who have O positive blood could easily have a child who is O negative. In fact, most children who are O negative have parents who are positive, since the +- combination is so much more common than the -- combination.

Answer 3

If you are both heterozygous +, the child has a 25% chance of being -. It will definitely be O. I guess most of you don't understand about heterozygosity. If not, please get in touch with me and I will explain it as it applies to a +/- rH factor. Your child may not be O+, as described above. *sigh* everyone is an expert, I guess. And I am working on my phD, thank you very much. I am sure some other women have their degrees also. What degree do you have? And Doula, I believe I just stated what is scientifically fact, although apparently you are longer winded than I am. Incidentally, do you have your phD, or am I better educated?

Answer 4

O and O can only make O

so likely O+

EDIT- reason i said O+ is b/c she asked what was more likly Yes the child can be O- but its RARE blood type!!!

Answer 5

You can only be what the parents are and both of you have the same blood type.

Answer 6

I am O+ and the father of my son is also O+ and our son is also O+.

Answer 7

o+ your both o+ if the baby is anything else one of you isnt the childs parent

Answer 8

O+

Answer 9

Why are you asking these uneducated ****s anyway???? LOL You are just as well off asking your dog. I doubt any one of these women has a bachelor's degree.

Answer 10

That's a lock for O+
