An organism can be homozygousdominant, if it carries two copies of the same dominant allele, or homozygousrecessive, if it carries two copies of the same recessive allele. Heterozygousmeans that an organism has two different alleles of a gene.

Meaning: If the diploid organisms carry two copies of each gene, they may be identical alleles so called homozygous.
It carries: Homozygous carries similar alleles of a trait. E.g. RR, rr.
Type of alleles: Homozygous individual can carry either dominant or recessive alleles, but not both at a time.
Type of gametes produced: Homozygous individual can carry either dominant or recessive alleles, but not both at a time.

Meaning: But if the diploid organisms carry two copies of each gene, which can be different (dominant and regressive) alleles, can be said as heterozygous
It carries: Type of allelesHomozygous individual can carry either dominant or recessive alleles, but not both at a time.
Types of alleles: Heterozygous individual has both, i.e. one dominant and one recessive alleles.
Types of gametes produced: Two types of gametes are produced.
