I am blood type o neg. My mother is AB pos and my dad is 0 pos. Is your RH factor inherited?

Answer 1

Yes, but it is a recessive gene. Your mother and father both have a pos and neg gene. Since the neg is recessive, they both have pos blood. You have 4 possible gene combinations: ++, +-. +-, --. Only the last one results is a negative blood type. So that means that you must have gotten a neg gene from your mother and a neg gene from your father.

Answer 2

If you are O negative, one of your parents is wrong about their blood type (your mother), or, you are adopted.

your parents each contribute a gene to the "pool"

To be O negative your parents could be O, A or B, but not AB.

If you are type A you could have one A and an O or two AAs
If you are type B you could have one B and an O or two BBs
If you are type O you can only have two Os.

Negative rh is the same.

I went through this when my first son was born -- they mistyped him at the hospital. I am O- and My husband is B-. They told me my son was A- and I had a hissy fit. They were pretty embarrassed.

best,

ps. the last link I found will show you that for type, an O cannot be born of an AB parent.

Answer 3

Well, you did get most of it from your father, and the 25% of the O type blood comes from AB blood. This means you did get this from your mother and father, congratulations.

Answer 4

sure, it really is conceivable. fairly, in my case, both my father and mom are constructive blood sorts, yet ought to carry the recessive gene (+/-)there became actually a 25% i'd be Rh-. I used Punnett Squares to determine all of it out. So if the mummy is adverse (-/-) & the daddy is constructive with the recessive gene (+/-), there is also a 25% threat for the infant to be Rh-, and seventy 5% threat of Rh +. to make certain that someone to be Rh -, they want 2 "adverse" warning signs (-/-). If the dad is constructive (+/+), then there is not any possiblity that the newborn will be Rh-, because each blend will be (+/-). desire that helps!
