Final answer:
Genetic mapping is used to determine the linear order and distance between genes on the same chromosome. Genetic maps provide an outline for gene locations and estimate distances based on recombination frequencies. Physical maps provide detailed physical distance information between genes.
Step-by-step explanation:
The purpose of genetic mapping is to determine the linear order and the distance between genes on the same chromosome. Genetic maps provide an outline for the location of genes within a genome and estimate the distance between genes and genetic markers based on recombination frequencies during meiosis. Physical maps provide detailed information about the physical distance between genes.
