What is the term for one of two or more alternative forms of a gene?

• A. Chromosome
• B. Allele
• C. Locus
• D. Genome

Answer: (B)

The term that describes one of two or more alternative forms of a gene is "allele." In genetics, alleles represent different versions of the same gene that can produce variations in a trait. For instance, a gene that determines flower color in a plant may have one allele for red flowers and another for white flowers. The presence of multiple alleles for a single trait contributes to genetic diversity within a population. In contrast, the term "chromosome" refers to the structure within cells that contains genetic material, while "locus" denotes the specific location of a gene on a chromosome. The "genome," on the other hand, encompasses the complete set of genetic material in an organism, including all of its chromosomes and genes.
