Question

Quizplus · Accepted Answer

Genetic maps are based on frequencies of recombination between loci (points on a chromosome where DNA is located). These frequencies can be used to estimate the distances between loci on a chromosome, which forms the basis of a genetic map. While genetic maps can provide important information about the relative positions of genes on a chromosome, they do not always accurately correspond to physical distances between genes, which may be impacted by factors such as chromosome structure and DNA replication. Physical maps, on the other hand, are derived from direct analysis of DNA and are often more detailed and accurate than genetic maps.
