What did Mendel find in the F1 generation? A) 30% of the plants expressed the dominant trait.

B)a ratio of 3:1:3

C)100% of the pea plants expressed the dominant trait.

D)a ratio of 3:1

the answer is either D or C

Explanation:

Working with garden pea plants, Mendel found that crosses between parents that differed for one trait produced F1 offspring that all expressed one parent's traits. The traits that were visible in the F1 generation are referred to as dominant, and traits that disappear in the F1 generation are described as recessive.
