Not necessarily.
Of corse not.There are three allels for blood groups.
If a mother has blood group 0 positive and the father is also 0 positive can they give birth to a child with blood group 0 negative?
Absolutely ! If the father of each child has the same blood group - there is a likelihood the children will inherit the same blood group (but obviously different genetic fingerprints !)
Yes, this is possible the alleles for B-type are (I^B i ) or (I^B I^B ) for a perent to be O which alleles is (ii) the child should be (I^B i ) and in this way the child got the (i) from father, and I^B from mother.
There is no disease caused by parents having the same ABO blood group.
Yes if both have the same blood group , the child at birth will have trouble.
It is actually better if you have the same blood group.
Yes of course all blood types produce the same species of genes it just will help determine what blood type your child will have.
yes, but the father may also be from another blood group, still with the same rh factor, such as B-, AB-, O-, that is, he will definitely have a blood group with the negative one like you, even if the blood group is not the same.
Blood types are received from the mother and father, so the child can be the same type as the mother if the father's type allows it.
It may similar or not.If both parents are O.Child is always O.If mother or father is AB,child is A,B or AB.
Yes, It is possible. But most of the time the child would have the same type of blood.
