Final answer:
If your blood clumps when mixed with anti-Rh sera and anti-B sera but does not clump when mixed with anti-A sera, your blood type is A-negative.
Step-by-step explanation:
Based on the information provided, if your blood clumps when mixed with anti-Rh sera and anti-B sera but does not clump when mixed with anti-A sera, your blood type is A-negative. This conclusion can be made because the clumping reaction with anti-Rh sera indicates the presence of the Rh antigen, while the lack of clumping with anti-A sera indicates the absence of the A antigen. Therefore, your blood type is A-negative.
