Mary can only receive blood from O+ & O- blood group but not from her husband (B-) or daughter (B+).
<h2>Description of Mary's blood group</h2>
Mary's blood group is O+ as her husband is B- and her daughter is B+.So, it can be said that the daughter's positive(+) antigen should come from her mother (Mary).
AS O blood groups lack A and B antigens, it can donate blood to all other groups and cannot receive from all groups as it has A and B antibodies in the serum.
<h3>Universal Donor</h3>
- Blood donors with type O- (O negative) red blood cells are known as universal donors, because their red blood cells may be used by people of any blood type.
- Transfusions from O-positive(O+) or O-negative(O-) blood types are the sole options for those with O-positive (O+) blood.
Therefore it can be concluded that Mary's blood group is O+ and she can receive blood from O+ and O- groups only.
