Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand blood group discovery.
The ABO blood group system is one of the most important discoveries in human genetics.
Step 2: Identify discoverer.
Karl Landsteiner discovered the ABO blood group system in 1900.
Step 3: Evaluate Mendel.
Mendel proposed laws of inheritance but did not discover ABO system.
Step 4: Evaluate Morgan.
Morgan worked on linkage and Drosophila genetics.
Step 5: Evaluate Bernstein.
Bernstein worked on genetic basis of blood groups but did not propose system.
Step 6: Conclusion.
Thus Karl Landsteiner is correct answer.
