Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding genetic tools.
In genetics, different methods are used to predict inheritance patterns and gamete combinations.
Step 2: Checkerboard method concept.
The checkerboard method refers to the Punnett square technique, which is used to calculate all possible combinations of gametes in a genetic cross.
Step 3: Contribution of Reginald Punnett.
Punnett developed this graphical method to predict genotype and phenotype ratios in offspring.
Step 4: Evaluating other options.
- Morgan: Worked on linkage and chromosome theory.
- Mendel: Father of genetics but did not develop checkerboard method.
- Correns: Rediscovered Mendel’s work.
Step 5: Logical reasoning.
Since checkerboard method directly refers to Punnett square, it is attributed to Punnett.
Step 6: Final conclusion.
Therefore, the correct answer is Punnett.
