Answer:
One of the possible forms of a gene occupying the same locus is referred to as an allele. An allele represents a specific variant or alternative form of a gene. Genes are located on specific positions called loci on chromosomes, and these loci can have multiple alleles. Each allele can have different genetic information, leading to variations in traits or characteristics expressed in an organism. For example, the gene for eye color may have alleles such as "brown," "blue," or "green," with each allele determining a specific eye color phenotype. Individuals typically inherit two alleles for each gene, one from each parent, and the combination of alleles determines the genotype and the observable traits of the organism.
