What are the major blood groups identified in forensic serology?

• A. A, B, AB, C
• B. A, B, O, Z
• C. A, B, AB, O
• D. A, C, AB, O

Answer: (C)

The major blood groups identified in forensic serology are indeed A, B, AB, and O. These blood types are determined by the presence or absence of specific antigens on the surface of red blood cells, which is a crucial aspect when analyzing blood evidence at crime scenes. Blood group A has the A antigen, blood group B has the B antigen, blood group AB has both A and B antigens, and blood group O has neither antigen. This system is integral to blood transfusions and forensic investigations since it helps in determining the compatibility of blood and aids in the identification of individuals based on biological evidence. In forensic applications, the classification of blood into these groups helps forensic scientists in narrowing down suspects or identifying victims when blood samples are collected. Other options that include groups such as C or Z are not recognized as valid blood types in the ABO blood group system used in forensic serology. Therefore, C is the correct choice, highlighting the established blood group classifications that are essential for forensic analysis.
