Question

The table given below is related to the checkerboard of dihybrid F\(_2\) progeny of Mendel’s experiment. Identify the correct combinations:

• A. I and II
• B. II and IV
• C. III and IV
• D. I and IV

Hint:

A dihybrid cross involves two traits and follows a 9:3:3:1 ratio in the F\(_2\) generation.

Answer 1

The Correct Option is D

Step 1: Understanding Dihybrid Cross and Phenotypes

- Dihybrid cross follows the 9:3:3:1 ratio for phenotypic expression.
- The number of genotypes determines dominant or recessive traits in the F\(_2\) generation.
- The correct genotype matches are I and IV.
