Organism with two alleles that are the same (TT or tt) Dominant Heterozygous Hybrid Homozygous

## Step 1<br />The problem is asking for the term that describes an organism with two identical alleles. In genetics, an allele is a variant form of a gene. <br /><br />## Step 2<br />When an organism has two identical alleles, whether they are both dominant (TT) or both recessive (tt), it is referred to as homozygous. <br /><br />## Step 3<br />The term "homozygous" is used to describe an organism that has two identical alleles for a particular trait. <br /><br />## Step 4<br />The terms "Dominant", "Heterozygous", and "Hybrid" do not accurately describe an organism with two identical alleles.
