Verified step by step guidance1
Understand that in genetics, a gene can have different forms or variations that determine specific traits.
Recognize that these different forms of a gene are called alleles, which are alternative versions of the same gene.
Differentiate between related terms: 'genome' refers to the complete set of genetic material, 'phenotype' is the observable trait, and 'karyotype' is the chromosome composition.
Conclude that the correct term for the gene form of a trait is 'allele' because it specifically denotes the variant form of a gene responsible for trait differences.
Remember that alleles can be dominant or recessive, influencing how traits are expressed in an organism.
