more on the blood, not rh though.

No.
The blood type is determined by two genes.
AA produces blood type A
Ai produces A as well
AB -- AB
BB -- B
Bi -- B
ii -- O
"i" is basically a broken gene. O blood type is when there are no "tags" on the red blood cells.
Using a Punnet Square, crossing ii and ii produces in all cases ii children. So, two parents with O cannot have an A type child.

Absolutely not.
As far as my understanding goes, O blood is the most recessive blood type, and the carrier must carry two O genes, so if both parents were O, then that would mean the child would receive nothing but O's passed along, which means they would end up with O blood aswell.

Yep. DNA learn have shown that blood typing is valueless in determining parentage. you might have a blood variety that neither discern has, yet according to probability your grandparent or maybe super-grandparent had. the two one in all my mothers and fathers are O valuable and 3 individuals are O unfavorable. We already knew that my grandmother replaced into O unfavorable (which replaced into why she in basic terms had one living toddler). My bro is a valuable and it appears that evidently my mom's paternal side of the family individuals has assorted those with variety A, subsequently the place that got here from (undesirable grammar, sorry).

No, O is recessive so a parent with O blood would only be able to give an O to the child, therefore the child would be O.

It is not biologically possible... my mom is O- and my dad is O+. I am O- and my brother is O+...if both parents are type O, then they don't have the genes for any other blood type...hope i was able to help.

no, one parent has to have A type blood for the child to have it .only O from both parents makes baby o type

No, since the genes for O blood are both recessive, it requires both alleles to be O, leaving no room for alleles for A, according to college biology.

No, both parents have the genotype ii, you would need the Ai or AA genotype to have an A- baby

There is no way to have a child A-. Someone either cheated or was adopted.
