Verified step by step guidance

Understand the concept of alleles: Alleles are different forms of a gene that are found at the same locus on homologous chromosomes. Each individual inherits one allele from each parent.

Define homozygous: Homozygous refers to a condition where both alleles for a particular gene are identical. For example, if both alleles code for blue eyes, the individual is homozygous for that trait.

Compare homozygous to heterozygous: Heterozygous refers to a condition where the two alleles for a gene are different. For example, one allele may code for blue eyes and the other for brown eyes.

Eliminate incorrect options: Recessive and dominant describe the expression of alleles, not their similarity. Homologous refers to chromosome pairs, not alleles. Dissimilar is the opposite of identical, which does not fit the description.

Conclude that the correct term for identical alleles in a gene pair is 'homozygous'.
