Autosomal chromosomes data

Despite mounting genetic evidence implicating a recent origin of modern humans, the elucidation of early migratory gene-flow episodes remains incomplete. Geographic distribution of haplotypes may show traces of ancestral migrations. However, such evolutionary signatures can be erased easily by recombination and mutational perturbations.
A 565-bp chromosome 21 region near the MX1 gene, which contains nine sites frequently polymorphic in human populations is unaffected by recombination and (...)
