Linkage of markers can help identify particular polymorphisms within the genome. These polymorphisms indicate slight changes within the genome that may present nucleotide substitutions or rearrangement of sequence. When developing a map it is beneficial to identify several polymorphic distinctions between two species as well as identify similar sequences between two species.
Markers linked to specific genetic variations within a genome can help pinpoint these variations, which may involve nucleotide substitutions or rearrangements in the sequence. When constructing a map, it is advantageous to identify multiple polymorphic distinctions between two species as well as similar sequences between two species.
