Which term describes different forms of the same gene?

• A. Chromatids
• B. Alleles
• C. Genotypes
• D. Phenotypes

Answer: (B)

The term that describes different forms of the same gene is alleles. Alleles are variations of a gene that occur at a specific location on a chromosome. For example, if you consider a gene that determines flower color, one allele may code for red flowers while another allele might code for white flowers. These variations contribute to the genetic diversity within a population and can influence traits observed in organisms.

Other terms offer different meanings: chromatids refer to the two identical halves of a duplicated chromosome, genotypes represent the genetic makeup of an individual regarding a particular trait, and phenotypes are the observable traits or characteristics that result from the interaction of the genotype with the environment. Understanding the role of alleles is fundamental in genetics, particularly in studying inheritance patterns and variations among individuals.
