Mendel selected true breeding tall (TT) and dwarf (tt) pea plants. Then, he crossed these two plants. The seeds formed after fertilization were grown and these plants that were formed represent the first filial or F1 generation. All the F1 plants obtained were tall.Then, Mendel self-pollinated the F1 plants and observed that all plants obtained in the F2 generation were not tall. Instead, one-fourth of the F2 plants were short.From this experiment, Mendel concluded that the F1 tall plants were not true breeding. They were carrying traits of both short height and tall height. They appeared tall only because the tall trait is dominant over the dwarf trait.
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
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.
Gregor Mendel described dominant traits as those that are expressed when present, masking the effect of recessive traits. Recessive traits are only expressed when two copies of the allele are present. Mendel's work laid the foundation for understanding inheritance patterns and the concept of genetic dominance.

he called the observed traits dominant and the disapear traits recessive.
Mendel called the more common traits "dominant" and the less common ones "recessive."-Sami. (:

did research on dominant and recessive traits.
I believe that you mean Gregor Mendel. He used peas to show dominant vs. recessive inheritance by noting their flower color. His observations were unappreciated for many years, but we now know that he was the first to systematically show the relationship between inheritance of traits, and how some traits are dominant over other traits.

Recessive traits are only expressed when two copies of the allele are present. Mendel's work laid the foundation for understanding inheritance patterns and the concept of genetic dominance.
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.
