Haplotype convergence

From Wikipedia, the free encyclopedia

[edit] haplotype convergence

A terminology used in DNA studies. Basically the haplotype "distribution" within one lineage overlaps with the haplotype "distribution" of another lineage - its like overlapping branches from two different trees. The more likely reason for your match is convergence (coincidence) or because you share a common haplotype. Convergence: Mutation is a random process and over thousands of years can occur in different lines so that by coincidence different "lines" end up with "matching" haplotypes. This accidental agreement is called convergence. (The more markers that are tested, the less likely it is that convergence will be observed).[1]
