When Mendel cross-fertilized P generation plants that had different traits, all F1 plants had the trait of one or the other P plant. This is because the F1 plants are heterozygous for the trait, meaning that they have one copy of the dominant allele and one copy of the recessive allele. The dominant allele is expressed in the phenotype, while the recessive allele is not.
