HapMap

(hăp′măp′)
n.
A database of common genetic variants in human beings from various regions of the world, the result of an international project to describe patterns of genetic variation and their relation to various diseases.

HapMap

HapMap

(hap′map″) [ hap(lotype) map]
A record of the presence of single nucleotide polymorphisms (alleles) on the chromosomes of some individuals but not others. It is used to identify the inheritance of diseases that do not follow simple mendelian genetics.
