Sounds like a medical question. Before believing anyone on here, I'd suggest asking a medical professional. A.K.A. Doctor.

Yes. Positive type blood is genetically dominant. For every trait we have, we have two alleles (pieces of genetic info.). One comes from mom and one from dad.
A positive person can have an allele for positive blood and one allele for negative blood - the positive allele wins in that person and their body makes positive blood.
Now, a positive person carrying an allele for negative blood can put a copy of that negative allele into a sperm or an egg.
If two positive people carry negative alleles, they can each put a negative allele in a sperm or egg and, by random chance, have a negative blood baby.

absolutely
the O part is a recessive gene and since both parents are O, the child could only be O
Since +ve is a dominant rH factor that determines that part of your blood type it can mask people carrying a -ve allele. So having a baby that is O -ve just means that each parent carries a -ve allele.

Yikes! How embarrasing for me. . . Apparently, a recollection of high school biology isn't enough -- I need to work on my reading skills too! I read the question backwards (flipped parents and child's rhesus factors) the first time.
Yes, this outcome is possible. . . if both parents carry a negative factor too. . .

well i know 2 negatives make a positive maybe that goes the other way around as well, but i think one of them would have to be a negative for this to happen

yes
Since the parents are both type O the ABO blood type can only be O.
Both parents are genotype OO
However, the Rh factor is a different matter.
In this case, both parents must be genotype (+-) - expressed as Rh pos
If either parent was homozygous genotype (++) the child would
be Rh pos since the Rh pos would be expressed

yes, easily, if they both carry the gene of o negative. its called dominant and recessive, and if positive is the dominant in ur family, then ur a recessive, but its totally possible

Yes the parents could have Ccddee and mother ccddeE or any similar combination.

i believe if one of the parents parents had o negative, yes.
