Which term describes different forms of a gene?

The term that describes different forms of a gene is "allele." Alleles are variations of a gene that can result in different traits. For example, a gene that determines flower color might have a purple allele and a white allele. These variations arise due to mutations in the DNA sequence of the gene.

In contrast, genotype refers to the genetic makeup of an individual, specifically the combination of alleles they carry. The locus is the specific physical location of a gene on a chromosome. Phenotype refers to the observable characteristics or traits of an organism that result from the interaction between its genotype and the environment. Understanding these terms is essential for studying genetic variation and inheritance.
