Title: Can a mother who is blood type B and father is O produce an A- child? Post by: rjt6250 on Aug 30, 2012 Is it possible for an individual who is A- to result from a B+ or B- mother and an O+ father.

Title: Can a mother who is blood type B and father is O produce an A- child? Post by: MikeLake on Aug 30, 2012 No, there are 2 alleles that controll blood type:
B type blood is: "I^Bi" or "I^BI^B" O type blood is: "ii" A typle blood is: "I^Ai" or "I^AI^A" The offspring must have an allele for the blood type from each parent, it can not inherite any combinations of alleles that would allow the child to have A type blood. Title: Can a mother who is blood type B and father is O produce an A- child? Post by: RJW on Aug 30, 2012 my answer is a BIG NO.. well i think so.. because, usually the child always get the blood type from the father, or sometimes from the mother, so where did the letter A came from..
Title: Can a mother who is blood type B and father is O produce an A- child? Post by: robintedd on Aug 30, 2012 NO.
A mother with type B has the alleles IB-IA or IB-i The father is i-i (IA-IB = AB, IA-i= A, IA-IA= A, IB-IB= B, IB-i= B, i-i= O) The father gave an i allele (recessive) Mom gave an i (child i-i type O) or IB (child IB-i, type B) Can't determine rhesus factor (+/-) from info given.

Title: Can a mother who is blood type B and father is O produce an A- child? Post by: mikejuies on Aug 30, 2012 No, A and B signify 2 different surface marker proteins on the red blood cells. O is a lack of any proteins. So if the parents are B and O then there is no A to give. + and - is another protein called RH factor. Only if the one of the parents have it will the child have it. + means you have the protein, - means you have no protein. So O- means absolutely no surface marker proteins.
Title: Can a mother who is blood type B and father is O produce an A- child? Post by: robjenkens on Aug 30, 2012 Absolutely not as in this case neither the mother or father have an "A" to contribute to the offspring.
Title: Can a mother who is blood type B and father is O produce an A- child? Post by: irina on Aug 30, 2012 not possible, since the father is type O, the mother has to be type A or AB to produce an offspring that is type A
Title: Can a mother who is blood type B and father is O produce an A- child? Post by: $abood$ on Aug 30, 2012 Only if the father is homozygous for the rare "Bombay phenotype" blood group and it's masking his i^A allele. This is possible but extremely unlikely. It's far more likely that "father" isn't the biological father, or that the lab screwed up the blood test for one of these people.
