Do parents and their children have to have the same blood type?

Question

if one parent is A- and the other parent is o+ can the child be o- with a RH- factor?

Answer 1

yes the child could be O-. If you have the right genes it is possible. You couldnt have any form of B or AB but if you have the right combination of genes A- and O+ could have a child with O-

Answer 2

yes they do because DNA is past down through the fathers sperm and the mothers egg.These normally give the baby there personal traits such as skin color ,body weight  ,height and rarely there behavior

Answer 3

not essential to worry but you must see that you are not of same family like nephew or neice

Answer 4

If one is A- and the other O+ then the baby will be A-, A+, O- or O+

Like for example i am A+, my ex is O- and our oldest son is A- because he got my A and his dads -

Answer 5

Here an example of my family...  My Dad B+ MY Mom A-  my brother AB+  me B-  so it comes out all weird....  hope the RH- parent is the man bc being RH- sucks (if you get prego)!

Answer 6

Yes, it can happen.  I had the same situation, 2 of our 4 children ended up with that blood type.  FOR SURE, same parents for each child, just in case you are wondering.

Answer 7

your blood type is the same as your parents. so for an example - my mums blood is B+ and my dads is A-. i could have either one of them or i might have AB blood. so its VERY unlikely i would have O or any others

Answer 12

Rh factor is possible, if the O+ parent has a recessive gene for no RH factor (thus is actually O+-, which gets expressed as a positive RH since that is a dominant gene). That parent could bequeath the + or the - gene, yielding another +- or a -- RH factor child. (What is impossible, is two RH negatives having a RH positive child, since neither "parent" would have a positive to pass on.)

Not sure about the A and O types, if that behaves similarly or not.

Answer 13

There's a formula to figuring out what blood type a child will be, based on the parents.  Unfortunatly, I dont know it.

Answer 14

Well, I am A- and my husband is O+. When I was pregnant I had to have the rogham shot for the RH factor. When our son was born he had my husband's blood type (O+)
