Abstract: Haplotype is a lineable combination of alleles at multiple loci that are transmitted together on chromosome or mitochondrion. In October 2002, the international HapMap project started and aimed at mapping the haplotype blocks of human being and discovering the Tag SNPs by determining the DNA sequence variation patterns, variation frequency and their relationship. This review summarizes the formation and distribution of the haplotype and the current three haplotype-analysis methods including the methodology of experiment, the deduction from pedigrees and the statistic method. When an allele linkage disequilibrium occurs, the genetic probability would be evaluated by haplotype. The importance of haplotype has been recognized and its application has been gradually increased in forensic sciences. The current focus on haplotype study in forensic science involves Chromosome Y, Mitochondrial DNA and Chromosome X, which are useful supplements of genetic marks.
