Which term describes the genome, containing all genes and other DNA sequences?

• A. Genotype
• B. Phenotype
• C. Genome
• D. Locus

Answer: (C)

The main idea here is what each term means in genetics. The genome is the complete set of genetic material in an organism, including all genes and the noncoding DNA sequences that regulate and organize those genes. It covers every part of the genetic material, not just the genes themselves.

In contrast, genotype refers to the specific genetic makeup or allele combinations a person has at particular locations in the genome, not the entire genome. Phenotype is the observable traits that result from the genotype interacting with the environment. Locus is a specific location on a chromosome where a gene or marker sits. Because the description mentions all genes and other DNA sequences, the correct term is the genome.
