the dominant trait
The trait that is not expressed in the F1 generation resulting from the crossbreeding of two genetically different true breeding organisms is called a recessive trait. It is masked by the dominant trait in the F1 generation but can reappear in subsequent generations when two recessive alleles come together.
reappears in some plants in the F2 generation
Mendel used the term "dominant" to describe a trait that emerged in the F1 generation.
recessive trait
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both a dominant and recessive alleles. The recessive phenotype disappears in the F1 generation because all members of that generation carry a dominant allele. In the F2 generation, the recessive phenotype will reappear.
True
Mendel referred to the characteristic expressed in the hybrid F1 generation as the dominant trait. This trait masks the expression of the recessive allele in the heterozygous individual.
Mendel's F1 generation plants showed only one of the two traits present in the parental generation. This indicated that the trait expressed in the F1 generation was dominant, while the other trait was recessive.

The recessive trait phenotype disappears in a one-trait test cross in the F1 generation. This phenotype can reappear in the F2 generation.
