Homozygons
an organism with two alleles that are exactly the same
purebred
nn
No two people in the world are exactly the same except identical twins. Their chromosomes are exactly the same because the egg split in two and formed two identical embryos.
Alleles
Two of the same alleles for the same trait.
Two different alleles for the same trait are heterozygous. No, Its homozygous. This answer is incorrect as homo = same.
Alleles are the same trait
In genetics, homozygous means having two of the same allele whether it be two dominant alleles or two recessive alleles.
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 condition called in a case when you have a two different types of alleles is called as Heterozygous and when this is exactly the opposite that is when it has the alleles for the same source we describe such a condition as a Homozygous. This two terms are of most importance when you take the genetics
