What blood type should be the children?

Question

My 4 cousins have A+,0+,0+ and B-...

While my aunt is A+ and my uncle 0+,how come they have one child of each type and rhesus?

Answer 1

It's not possible for A+ and O+ to have a B-.....I'd keep my mouth shut and mind my own business.  I imagine your uncle already knows he's not the father of that child.

Answer 2

I dont understand how they got the B-, I thought if both parents were postive the kids had to be, but I really dont know for sure.

Answer 3

Maybe they were carrying a recessive gene for B- blood. Or maybe that kid is adopted, or has a different father.

Answer 4

If the parents have type A and O, there is NO way to get a type B child....might want to give the mailman a paternity test.

*edit*  sigh.....Trust me on this one....I have spent many years in college, and it's all simply figured out by doing a Punnett square.

Answer 5

Answer 6
