Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Wiener hypothesis.
Wiener proposed that the Rh blood group system is controlled by multiple alleles at a single gene locus.
Step 2: Number of alleles for Rh phenotype.
According to Wiener, 8 alleles determine the Rh phenotype in humans.
Step 3: Conclusion.
Hence, the correct number of alleles is 8.
