Final answer:
Both genetic linkage maps and physical maps are required to build a complete picture of the genome. Genetic maps provide an overview of the location of genes on a chromosome, while physical maps provide detailed information about the physical distance between genes or genetic markers.
Step-by-step explanation:
Both genetic linkage maps and physical maps are required to build a complete picture of the genome. Genetic maps provide an overview of the location of genes on a chromosome and use genetic markers to indicate their position. Physical maps provide more detailed information about the physical distance between genes or genetic markers. By combining the information from both types of maps, researchers can study individual genes more effectively.
