Verified step by step guidance1
Understand that a gene is a segment of DNA located at a specific position, called a locus, on a chromosome.
Recognize that genes can have different versions or variants, which are called different forms of the same gene.
Learn that these different forms of a gene found at the same locus on homologous chromosomes are called alleles.
Differentiate alleles from other terms: phenotypes refer to observable traits, homologous chromosomes are chromosome pairs, and codons are sequences of three nucleotides in mRNA.
Conclude that the correct term for two different forms of a gene at the same locus is 'alleles'.
