What is the expected phenotypic ratio in the F2 generation of a monohybrid cross?

What is the expected phenotypic ratio in the F2 generation of a monohybrid cross?

Correct Answer: 3:1

Step 1: Understand what a monohybrid cross is. It involves crossing two organisms that differ in one trait.
Step 2: Identify the dominant and recessive traits. The dominant trait is the one that appears in the offspring, while the recessive trait does not.
Step 3: In the F1 generation (first generation), all offspring will show the dominant trait because they inherit one dominant allele from each parent.
Step 4: When the F1 generation is crossed with itself, it produces the F2 generation (second generation).
Step 5: In the F2 generation, the offspring will show a mix of the dominant and recessive traits.
Step 6: The expected ratio of offspring showing the dominant trait to those showing the recessive trait is 3:1.
