Final answer:
If a type B woman whose mother was type O marries a type O man, the possible genotypes of their children are BO and OO. The possible phenotypes of their children would be type B or type O. The woman with type B blood can donate blood to individuals with blood types B and AB, but not to her husband with type O blood.
Step-by-step explanation:
Possible Genotypes and Phenotypes of Their Children
If a type B woman whose mother was type O marries a type O man, the possible genotypes and phenotypes of their children can be determined using the principles of inheritance for the ABO blood group. The ABO blood group system is determined by three alleles: A, B, and O. The B allele is dominant over the O allele. If the woman is type B, her genotype is either BB or BO. If the man is type O, his genotype is OO. Therefore, their possible genotypes for their children are BO and OO.
In terms of ABO blood group phenotypes, the possible phenotypes of their children would be type B (if the child inherits the B allele from the woman), or type O (if the child inherits the O allele from both parents).
Can the Woman Donate Blood to Her Husband?
The woman in this scenario has type B blood, which means she has B antigens on her red blood cells. The man has type O blood, which means he has no antigens on his red blood cells. Since the woman has B antigens, she can donate blood to individuals with blood types B and AB because they can accept B antigens. However, she cannot donate blood to her husband, who has type O blood and does not have any antigens to match with the B antigens of the woman.
