Verified step by step guidance1
Understand the concept of alleles: Alleles are different forms of a gene that can exist at a specific locus on a chromosome.
Recognize the term 'homozygous': An individual is homozygous for a gene if they have two identical alleles for that gene.
Differentiate between homozygous and heterozygous: Homozygous means having two identical alleles, while heterozygous means having two different alleles for a gene.
Consider the context of dominance: While homozygous refers to the alleles being identical, it does not specify whether they are dominant or recessive.
Apply the definition: In this context, the term that describes an individual with two identical copies of a gene is 'homozygous'.
