Physical traits are called?

• A. Phenotype
• B. Genotype
• C. Alleles
• D. Chromosomes

Answer: (A)

Physical traits are the observable characteristics an organism shows, and those are called phenotypes. The phenotype reflects the genotype—the organism’s genetic makeup—working with environmental factors to produce what you actually see or measure. Alleles are the different versions of a gene that can influence which phenotype appears, while chromosomes are the structures that carry the genes but aren’t traits themselves. For example, eye color is a phenotype that results from specific gene variants (alleles) on chromosomes, with the environment typically playing a smaller modulatory role.
