The SNP markers have emerged as essential resources for performing genetic linkage, association, and admixture studies. Both academic and commercial groups are developing large numbers of genome-wide SNP datasets. These databases are utilised for several studies involving both structural and functional genomics. Some studies viz. admixture mapping, population structure identification and quantifying genetic diversity requires a genome-wide small informative panel of relatively evenly spaced markers. These informative markers can distinguish the ancestral origins of chromosomal segments in admixed individuals and can delineate the ancestral origin of a particular population. Thus present study reviews existing methods to select ancestry informative markers and their comparative efficiency in inferring individual ancestry level. |
