Definition of Hapmap

HapMap is a tool that helps the researchers to determine the genes and genetic variants that are present in a human. It is also known as haplotype map and is developed by the International HapMap Project. The genetic material of all human beings is similar to each other to the extent of 99.5%. The risk of occurring disease is highly affected by the variations that are present in the genome.


The sites at which the DNA is varied at a single base (A, G, C, U) is known as single nucleotide polymorphisms. These SNPs are transferred in the form of blocks and the pattern of this SNP on the blocks is termed as a haplotype. The relation of the genetic variation with the disease is studied by HapMap.
