Gregor Mendel took two true-breeding plants with contrasting traits and cross-pollinated them, producing offspring with genes for both characteristics. He used selective breeding.
The aim of Gregor Mendel was to prove the laws of inheritance through his experiments with the breeding of pea plants.

Gregor Mendel:D
Gregor Mendel's theories are the basis for modern breeding techniques of plants and animals. Mendel was a German friar who experimented with breeding pea plants.

I think its cross filial generation...
Since the dominant allele in pea plant breeding is the tall allele, all of the offspring of this cross were tall. However, when he crossed two tall plants from the first filial generation, 75% of the second filial generation were tall, and 25% of the second filial generation were short, thus hinting at the mechanism of what we today recognize as genetic inheritance.
If Gregor Mendel did not use plants that were not true breeding, he would not have discovered heredity because there would not be any evidence that traits passed on to the next generation and that the offspring retained the traits of the parents.
one tall allele and one short allele
There is no evidence that Gregor Mendel created vicious bees. In fact he was unsuccessful at breeding them alltogether. This myth seems to have come about around 2001 in online publications and been copied without reference in unscrupulous sources.
