Rh positive means that the person carries the gene to express the Rh factor protein on the surface of their cells. Red blood cells have surface... Learn more about this topic: Rh Blood Group, Rh Factor & Erythroblastosis Fetalis from ...
any of a group of antigens on the surface of red blood cells, those having inherited such antigens being designated Rh + (Rh positive) and those lacking them, a much smaller group, being designated Rh− (Rh negative):transfused or fetal Rh + blood may induce a severe reaction in an...
These two blood groups are incompatible, that means that if they mix, deadly reactions can occur. That's why it's dangerous when an Rh negative woman becomes pregnant with an Rh positive baby. 这两种血型不相溶,也就是说如果它们混合在一...

Among Old World monkeys, including humans, the nostrils are usually closely appressed medially, and the fact that they typically open downward (or forward) is expressed in this infraorder's name: Catarrhini (catarrhine means “down-nosed”). The cartilaginous wings that support the sides of ...
Deoxyribonucleic acid was extracted from fetal tissue to determine the fetal RhD status by means of polymerase chain reaction. Antigen expression was also sought by analytic cytometric analysis (flow cytometry and immunocytochemistry) using a monoclonal anti-D antibody.Trophoblast was studied from various...
Blood types A and B are co-dominant. This means that if both the A and B alleles are present in a person, they will have the associated antigens from both of these blood types on their red blood cells. In co-dominance, neither allele is strong enough to masks the effe...
