In Mendel’s initial experiments, an example of the F2 generation would be:
A. 75 round seed plants to 25 wrinkled seed plants
B. 75 green seed plants to 25 yellow seed plants
C. 75 white-flowered plants to 25 purple-flowered plants
D. All of the above

All of the options listed represent examples of the **F2 generation. **Therefore, option ( D ) is correct.
What was Mendel’s experiment?
In Mendel's initial experiments, he conducted crosses between** true-breeding **parental plants with different traits, such as round vs. wrinkled seeds, green vs. yellow seeds, and white vs. purple flowers. The offspring of these crosses in the first generation, known as the F1 generation, all had the **same traits **as one of the parental plants, indicating dominance of one trait over the other.
Mendel then allowed the **F1 plants **to **self-pollinate or cross-pollinate with each other, which produced the F2 generation. The F2 generation exhibited a 3:1 ratio **of dominant to recessive traits, demonstrating the segregation and independent assortment of alleles. Therefore, all of the options listed represent examples of the F2 generation.

The correct answer is D: All of the above, as each option represents traits observed in Mendel's F2 generation experiments. Mendel noted a consistent 3:1 ratio of dominant to recessive traits in the F2 generation. This foundational work established the principles of inheritance in genetics.
