Step 1: Understanding \(F_1\) Generation.
The \(F_1\) generation refers to the first filial generation of offspring obtained by crossing two parental organisms with contrasting traits.
Step 2: Dominant and Recessive Traits.
In Mendel's experiments, the trait that appeared in the \(F_1\) generation (the offspring) was the dominant trait. The other trait, which did not appear, was the recessive trait.
Step 3: Conclusion.
Thus, the trait expressed in the Fâ‚ generation is the dominant trait.
