An organism with two alleles of the same type is known as homozygous. This means that it has two copies of the same gene variant. This can be either homozygous dominant (if it carries two copies of the dominant allele) or homozygous recessive (if it carries two copies of the recessive allele).

Here are the steps to determine if an organism is homozygous:

1. Identify the two alleles that the organism has for a particular gene. This information is usually given in a genetics problem or can be determined through a test cross.

2. Compare the two alleles. If they are the same, then the organism is homozygous for that gene.

3. If the organism is homozygous dominant, it will display the dominant phenotype because it has two copies of the dominant allele.

4. If the organism is homozygous recessive, it will display the recessive phenotype because it lacks the dominant allele.

5. If the two alleles are different, then the organism is heterozygous for that gene.

Remember, alleles are versions of a gene that can come in different forms. For example, for the gene that determines eye color, one allele might carry the information for blue eyes, while another allele might carry the information for brown eyes.
