how about O type?
2006-11-03 02:39:17 · update #1
As everyone has told you the only type not possible is O
because to get type 0 blood which is recessive you would need a recessive allele from each parent. Obviously if you are AB (which are codominant) you do not have a recessive allele. The child could Inheret either the A alle or the B allele and would end u p with type A, B or AB blood depending upon the allele passed by the other parent.
I see you also want to know if there are any blood types not possible for the children of a person with O type blood to get. Yes, a person with O type blood cannot end up with a child with AB blood because they have 2 recessive alleles. They could end up with children with A B or O phenotypes

If both parents are type AB, then only type O is impossible. Each parent must contribute either A or B, while type O is possible only when both parents contribute O. It is, however, possible for the child to appear to have type O blood in the rare situation that he or she has the Bombay phenotype. Blood tests that are not looking at this blood system will show that the blood is type O, regardless of the child's genetic blood type.

Crossing chromosomal DNA, only O type isn't possible. Its either any form of A, B or AB again.

many times, if the two mom and dad are blood sort O, then the youngster would be blood sort O. this is available, nonetheless uncommon, for the two mom and dad to be blood sort O and the youngster be sort A, B or AB. this might require a mutation from the two confirm interior the germ cells (sperm or egg) to alter the germ cellular gene from an O blood sort to an A or B blood sort with the intention to have a infant with A or B blood sort. As an aside, it would be very uncommon for somebody to finally end up with AB as the two mom and dad might have ought to have a mutation interior the germ cells-one for the A and the different for the B blood sort. additionally, lab blunders is usually a attention (contained while it comes to your blood typing, and the blood typing of your mom and dad). with the intention to rule out labe blunders, you will ought to have them re-verify their varieties and you re-verify yours and see if the outcomes are an identical. additionally, this is incredibly helpful to envision with your medical expert for extra suggestion.
