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.
The brothers have different alleles. They received different alleles from their parents
Alleles that are the same = homozygous Alleles that are different = heterozygous
The genotype that has two different alleles is heterozygous
Different versions of the same gene are called
The different molecular versions of the same gene are called alleles.

When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?

The answer is: hybrids
A population with different alleles will have traits
Alleles that are the same = homozygous Alleles that are different = heterozygous
If Mendel's experiments were not true breeding, then he would not be ablt to tell the recessive alleles showed up in the F2 progeny. Since the F1 generation would have showed the dominant trait regardless, the only way to show the recessive alleles carry to the F2 is to have true breeding parents.
Alleles
The genotype that has two different alleles is heterozygous
