Which means you got one O from your mother and one O from your father, along
with one positive gene from one parent and either a positive or negative gene
from the other parent.
++ is a positive Rh (meaning you get one positive gene from your Mom and one
from your Dad)
+ - is also a positive Rh (meaning you got one positive gene from one parent
and a negative gene from the other)
- - is a negative Rh (meaning you got one negative gene from each parent)

Tabitha,
I don’t understand what you mean!! I am “O” positive!!

another sister, but I don’t know their blood types. I guess you might say I
have an ABO family!!
As far as Rh factor your dad would have to be + - (which manifests as
positive). Your dad gave you one negative gene and your Mom gave you one
negative gene which made your Rh factor negative.

My naturopath said if both parents are O, kids are O for sure so I haven’t
had the kids tested. Just in case you hadn’t done the math you double O
parents.

<< In Dr. D’s interesting fact yesterday he said that the O is a recessive
gene
and the way I understood it is that if you have an O parent and an A or B
parent the child would be an A or a B… so I’m wondering how I can be an O
neg. if my mom is an O and my dad an A
I think I can answer this one. Each parent has two blood type genes, one
from each of his/her parents (your grandparents). Your Mom is an OO because
the only way you can have an O is to have 2 O genes, one from each parent.
OK now listen carefully. There are two ways a person can be an A. The
person can have AA (meaning he got one A gene from each parent) or AO
(meaning he got one A gene from one parent and one O gene from the other
parent). THE SECOND SCENARIO IS YOUR FATHER. So when your Mom got pregnant
with you:

1) She could only give you O genes (that’s all she had) so she gave you one O
gene
2) Your Dad had a choice, so to speak, and could have given you either an A
gene or an O gene. Since he gave you the O gene, you have two O genes (OO)
and are type O.
The same thing is true with my daughters. I am O and hubby is B. One
daughter is O (she got one O gene from each of us) and the other daughter is
B (she got an O gene from me and a B gene from her father, making her B.
The same is true with Rh factor. You inherit one gene for that from each
parent:
++ (one positive gene from each parent) means you are positive
+- (one positive gene from one parent and one negative gene from the other)
means you are positive
- - (one negative gene from each parent) means you are negative.
So in the case of my daughter the B, she is BO. When she has children, she
can pass on either her B gene or her O gene to her children, but only one at
a time. She still has the O gene even though it’s not being expressed right
now.

This explains my question in the previous post.
Thanks,

I wonder that also. I am an O and my son’s father is an A, but my only son
is an O.

Leslie what Dr. D means is this…
Blood types come from two parents so each passes their “type” along.
So basically blood has two components (for simplicities sake).
So technically blood type are like OO (O), AA (A) AO (A), BB (B) ,,, etc.
Now notice that AO is classed A that is what he means by recessive.. the parent
still carries the O gene however he is classed as A.
Now your Dad probably has AO (he probably had one O parent and one AA or AO
parent). And your mom OO parents.
Your dad probably passed the O gene and your mom an O gene = you O.
The odds are like this I’ll use O1 and O2 for the order of gene….
MOM DAD YOU
O1 A1 A
O2 A1 A
O1 O2 O
O2 O2 O

Hope this helps Crystal.
