A new gene persists in evolution if it is favoured by natural selection. What decides whether a new concept or idea will persist? We simply do not know. Certainly it is not its sheer usefulness to mankind, or we should have had universal peace for many centuries by now. But there is ...
E and e antigens of the Rh blood group.The D antigen was further detected with an indirect antiglobulin test.RHD zygosity was detected by sequence-specific primer PCR method.All exons and flanking intron regions of the RHD gene were sequenced.Results The samples were determined as weak D ...
DNA sequencing showed that the 4 cases were heterozygous for 17C>T mutation in exon 1, 29G>C mutation in exon 1, 1212C>A mutation in exon 9, and IVS4+ 5G>A mutation in intron 4 of the RHD gene, respectively. According to the rule of Rhesus Base Nomenclature, the 4 samples were ...

This blood group system is considered the most important, because of the high risk of a severe haemolytic transfusion reaction if ABO incompatible blood is transfused. There are three antigens in the ABO blood group system, A, B and H. The ABO gene is located on chromosome 9 and has thre...
For blood type, we see codominance. Which two blood types are codominant? Which blood type is recessive? What are the 3 alleles of the gene that control blood type? A. IAIBI B. ABO C. IAIAIBI What blood type is impossible for the parents of a child with AB blo...
