homozygous
When there are heterozygous alleles for a gene thy code for a different expression of the gene. For example, the gene to taste PTC paper is a single gene trait. A person will have two copies (or alleles) for that gene (one from their mothers DNA, one from their father). There are two possible expressions for this gene - either you can taste the chemical or you cannot. When one allele is for tasting, and the other for not tasting, this is known as heterozygous. Both alleles are relating to the same gene but they giving different instructions and are thus not identical. When this happens, the dominant gene wins - in this case tasting is expressed. If the alleles are identical, they are known as homozygous and they are identical.
An organism that has two identical alleles for a trait is known as a homozygote or a homozygous organism.
A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.
An organism whose alleles for traits are identical is said to be homozygous for that particular trait. This means it carries two identical alleles for that specific gene. For example, if an organism has two alleles for blue eyes and both are the same, then it is homozygous for blue eyes.
Actually, heterozygous individuals have two different alleles for a particular gene, with one allele inherited from each parent. This contrasts with homozygous individuals, who have two identical alleles for a specific gene.

No, all alleles at a specific gene locus are not identical. Alleles are different forms of a gene that can result in different traits or characteristics. Each individual inherits two alleles for each gene, one from each parent. These alleles may be the same (homozygous) or different (heterozygous).
homozygous(different gene)-Rr heterozygous(same gene)-RR,rr
the organism that have two identical alleles would be called homozygous for that particular gene.
i think what it is having two identical alleles for a particular gene
An organism that has two identical alleles for a trait is known as a homozygote or a homozygous organism.
Alleles can be either dominant or recessive. They can be identical or different for any given gene in a somatic cell, and can represent alternative forms of a gene.
A recessive gene A recessive gene makes it harder for genes(or traits) to be passed on from parents to daughters.
