An organism with two identical alleles for a given trait is

The term homozygous is used to describe an organism which has the same or identical alleles for a particular trait located at similar loci on paired chromosomes (i.e. homologous chromosomes). In a diploid organism, there are two sets of chromosomes. One of the sets comes from the mother and the other set from the father. Each maternal chromosome has a corresponding paternal chromosome to match with based on their loci. When the loci in the matching chromosomes bear the same alleles, it is described as homozygous. It means that the alleles code for the same trait.
