Geneticist make 3 types of maps
All three locate loci along molecules of DNA ( Chromosomes)
Although they map the same information they reveal different levels of detail and use different units of measure.
Maps constructed from recombination data and distance measured in Centi Morgan. Distances are not accurate, they are relative.
Molecular counterpart of linkage maps and distance measured is actual number of base pairs that separate 2 genes.
Shows the order of nucleotides in a piece of DNA. Sequence information isderived from genome sequencing projects.
