Question

In the F1 generation (RrIi), if recessive genes are crossed, how many zygotes will form?

• A. 4
• B. 8
• C. 16
• D. 32

Hint:

Use the Punnett square for analysis.

Answer 1

The Correct Option is C

A dihybrid cross, specifically RrIi × RrIi, adheres to Mendelian inheritance. A Punnett square analysis reveals 16 possible zygote genotypes, represented by a 4x4 grid.
