What does the term 'genotype' refer to?

• A. The physical appearance of an organism
• B. The genetic constitution of an individual
• C. The group of genes expressed under certain conditions
• D. The overall fitness of an organism

Answer: (B)

The term "genotype" refers specifically to the genetic constitution of an individual. It encompasses the alleles present at specific loci that an organism carries, essentially representing its genetic blueprint. This genetic makeup can determine various traits and characteristics, although environmental factors can also influence how these genes are expressed in the organism's physical manifestation, known as the phenotype. Understanding genotype is crucial because it provides insights into inheritance patterns, genetic diversity, and the potential for variation within a species.
