Mendel’s F1 generation plants were dominant .
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.
The F1 generation helps scientists determine which alleles are going to be recessive and which will be dominant in further crosses.
F1 generation is the first filial generation, whereas F2 generation is the second filial generation obtained by crossing the F1 generation.
