In panel results, which cells are identified as homozygous for C?

• A. 1, 2, 3
• B. 1, 2, 9
• C. 3, 4, 7
• D. 7, 8, 10

Answer: (B)

In analyzing panel results for blood group typing, identifying homozygous reactions is crucial for understanding an individual’s genetic makeup concerning specific antigens. When we refer to a cell being homozygous for antigen C, it means that both alleles at the relevant gene locus encode for the same antigen. The interpretation of panel results usually involves examining the agglutination reactions observed in the presence of various anti-sera for specific antibodies. Cells that agglutinate strongly in the presence of anti-C antibody indicate that they express the C antigen, while those that do not show any agglutination would suggest the absence of that antigen. In the context of the choices provided, choosing 1, 2, and 9 as the correct answer implies that those cells consistently exhibit strong positive reactions with anti-C antisera, indicating they are homozygous for antigen C. This consistency would be necessary to confirm the homozygosity since the result must hold across multiple assays or tests. Selecting this answer reflects a detailed understanding of how to read and interpret panel findings, specifically recognizing that homozygous cells will display a uniform and expected agglutination pattern with antisera targeting antigens present on the surface of those cells. Therefore, this understanding
