Just curious- My son is O- blood type and I know mine is something-(negative) ?

Question

but what would my and his father's type be? Would they both have to have been O- also?

I don't understand- I am just curious. I am giving blood soon I'm sure they'll tell us but I am wondering.

Thank you!

Answer 1

ask a doctor

Answer 2

If your son has O- blood, then you and his father have O- blood.  If one of you were an A or a B, then it would cancel out the O.  

You should know that O- blood is very sought after because it can be used for anyone, A- B- or AB-.  It is very versatile, and very precious, especially for AB- people who can only take AB- blood (which is rare) or O-.  You might consider donating on a consistent basis.  It would really be a good deed that would help a lot of people!

Answer 3

Blood group can be the same as either the mother, father or both.

The main blood groups are A+; A-; B+; B-; O+; O-; AB+; AB-

The Plus or minus sign refers the Rehsus factor found it the blood ie it is positive or negative.

People with A blood can give to A

People with B blood can give to B

People with AB blood can give to A or B

People with O blood can give to any group

Does this help any??

Answer 4

It is most likily that you are also O-, but you could also be a rare AO- or BO- and have passed on the O type.

Answer 5

I'm A-ve, hubsband & son both O+ve, so no real reason unless you want the whole Mendle's theory stuff!!! Is it important for health reasons? If not, accept that you're healthy!!  

Answer 6

You can't tell what your blood type is if your son is O, it doesn't mean that you will be O as well.

Answer 7

because O is a recessive gene, as long as both you and his dad have this gene, then you two can show as A or B  but your son could be O. If he's negative and so are you, then it means that his dad also has a negative gene, because it's also recessive.
