    In genetics when an organism is heterozygous that means that it contains 2 different alleles for a specific gene, heterozygous refers to the genotype

    Homozygous means the organism carries 2 of the same alleles.

    For example there are two alleles for the gene of eye color

    B - is the dominant allele for brown eyes

    b - is the recessive allele for blue

    So if a person's genotype is like Bb then he is heterozygous

    but if he is like BB or bb then he is homozygous
