Mendel called alleles/genes factors.
Gregor Mendel called them factors, or traits.
The answer is: hybrids
One from Male, and one from Female
Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.

He discovered dominant and recessive alleles. He also bread and tested 29,000 pea plants
Because they were simple, easy to recognise phenotypes controlled by one set of alleles

Each time Mendel studied a trait, he crossed two plants with different expressions of the trait and found that the new plants all looked like one of the two parents. He called these new plants hybrids because they received different genetic information, or different alleles, for a trait from each parent.
I don't know exactly for how long did he study pea plants but I do know that his work is of immense value in the field of genetics.Gregor Mendel was the first person to introduce the concept of alleles in genes and their affect on offspring's genotype or phenotype.Modern day genetics still and will continue to use Gregor Mendel's work to understand concepts of genetics.
As found on the Wikipedia page on Gregor Mendel: "This study [Mendel's pea plant experiments where he crossbred two pea plants, one purple and one white and from there it demonstrated dominant and recessive alleles] showed that one in four pea plants had purebred recessive alleles [usually white], two out of four were hybrid and one out of four were purebred dominant. His experiments led him to make two generalizations, the Law of Segregation and the Law of Independent Assortment, which later became known as Mendel's Laws of Inheritance." Breeding two of the pure, purple plants would yield only pure purple plants, however the hybrid ones (which would look like the pure ones) would yield three purple looking ones (one was pure, the others had recessive alleles) and the last one would be white (all recessive alleles) thus Mendel was eventually able to see that recessive alleles didn't just crop up randomly, they were traits that were suppressed and passed on invisibly to the next generation of plants.
