Mapping Population Development
The principle of genetic mapping is mainly based on sampling recombination frequency for the given genes (or markers) that are available in the mapping population. Mapping population consists of individual progenies that are originated from two parents of one species or related species. Hence, the first step in linkage or genetic map construction is development of mapping population. It is considered as key genetic tools/resources in linkage map construction since they are used to identify genetic loci that influence the expression of phenotypes and to determine the recombination distance between loci.
