Homozygote refers to a pair of identical alleles of a gene. It means the organism or the cell is having same allele for a gene. It can be homozygous dominant or homozygous recessive[1].
For example, for a certain gene, "A" represents the dominant allele and "a" represents the recessive allele. The combination of "AA" and "aa" will be a homozygote allele pair which represents homozygous dominant and homozygous recessive respectively. Homozygous recessive genotypes are used in "test cross" for the analysis and determination of a unknown genotype.[2]
