The correct answer is homozygous.
Homozygous is a term for genotype that has identical alleles for a single trait.
An allele is a form of a gene and diploid organisms have two alleles for a given trait: one inherited from father and one for mother.
Homozygous alleles may be dominant or recessive. A homozygous dominant has two dominant alleles and expresses the dominant phenotype (expressed physical trait), while homozygous recessive has two recessive alleles and expresses the recessive phenotype.
