Mendel referred to the trait that appeared in all first-generation plants as the "dominant" trait. In his experiments with pea plants, he observed that certain traits, such as flower color or seed shape, consistently overshadowed others in the offspring. The traits that did not appear in the first generation were termed "recessive." Mendel's work laid the foundation for the principles of heredity and genetics.
Mendel's experiments showed the characteristics of genes that express complete dominance--that is, traits where one allele is completely dominant over another, and the recessive allele does not appear in the phenotype at all. Some of the specific traits that Mendel was testing include pea color (yellow or green, with green being completely dominant) pea surface texture (wrinkled or smooth, with smooth being dominant) and flower color (pink and white, with pink being dominant.)
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.
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.
Gregor Mendel called the traits that disappear in the first generation recessive traits. These traits are not expressed in the offspring when there is a dominant trait present.
The ratio of dominant to recessive phenotype in the F2 generation of Mendel's experiment was 3:1. This means that for every 3 individuals expressing the dominant trait, there was 1 individual expressing the 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.

Yes, Gregor Mendel's principle of dominance stated that in the F1 generation, the dominant allele would mask the expression of the corresponding recessive allele. This means that only the dominant trait would be observed in the offspring.

f2 generation
Gregor Mendel called the traits that disappear in the first generation recessive traits. These traits are not expressed in the offspring when there is a dominant trait present.
Mendel proposed the concept of dominant and recessive traits, where recessive traits are masked in the F1 generation but can reappear in the F2 generation when two carriers of the recessive trait combine and show the trait. This is known as the Law of Segregation, where pairs of alleles separate during gamete formation, leading to the reemergence of hidden traits.
The ratio of dominant to recessive traits in the F2 generation of Mendel's experiments was 3:1. This is known as the phenotypic ratio for a monohybrid cross, where three individuals display the dominant trait for every one individual displaying the recessive trait.
recessive trait
he called the observed traits dominant and the disapear traits recessive.
