How are multiple forms of the same gene referred to?

• A. Chromatids
• B. Loci
• C. Alleles
• D. Genomes

Answer: (C)

The multiple forms of the same gene are referred to as alleles. Alleles are variations of a gene that arise due to differences in the DNA sequence. These variations can result in different traits or characteristics being expressed in an organism. For example, a gene that determines flower color may have one allele for red flowers and another for white flowers. This term is fundamental in genetics because it helps explain how traits are inherited and expressed. When an organism has two different alleles for a particular gene, it can exhibit dominant or recessive traits depending on the relationship between those alleles. In contrast, chromatids refer to the two identical halves of a duplicated chromosome, loci is the specific physical location of a gene on a chromosome, and genomes encompass the complete set of genetic material in an organism. Understanding the concept of alleles is crucial for studying inheritance patterns, genetic variability, and evolution.
