Two alleles expressing exactly the same information for a trait are described as homozygous.
An individual is homozygous for an allele if the two alleles are identical. Two normal alleles or two alleles with the same variation can both be present in a homozygous genotype. When an organism is homozygous, it signifies that it possesses two copies of the same gene allele.
If an organism possesses two copies of the same dominant allele, it is said to be homozygous dominant, and if it possesses two copies of the same recessive gene, it is said to be homozygous recessive. For instance, there are two variants of the gene for seed shape in pea plants: one form (or allele) for round seed shape (R), and the other for wrinkled seed shape (r).
