Homozygous Dominant
Image result for homozygous dominant definition
Definition of Homozygous Dominant. Many genes come in two versions: the dominant allele and the recessive allele. Since diploid organisms (like you and me) have two copies of each of our genes, we could have one of each allele and be heterozygous or have two of the same and be homozygous. :
Homozygous Recessive
An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene.
