Question

Suppose you have a plant with petals that are normally blue. Suddenly you see some white-petaled plants. You cross the white with the blue and you get all an F1 population that is all blue. In the F2 generation you see a ratio of 101:33 blue to white-petaled plants. What conclusion might you draw upon finding these results?

Answer 1

The experiment suggests that the trait for white petals is recessive and the trait for blue petals is dominant. The F1 generation was all blue, indicating the dominance of the blue trait. However, the F2 generation showed a ratio of 101:33 blue to white-petaled plants, suggesting that the white trait is still present, but at a lower frequency.

Step-by-step explanation:

In this experiment, it appears that the trait for white petals is recessive, while the trait for blue petals is dominant. When the white-petaled plants were crossed with the blue-petaled plants, the resulting F1 generation was all blue, indicating that the blue trait is dominant. However, in the F2 generation, there was a ratio of 101:33 blue to white-petaled plants, suggesting that the white trait is still present, but at a lower frequency.
