Haplogroup in the project

Haplogroup database project

Haplogroup w genetics - a group of similar due to common ancestry haplotypów, or series alleles genes located in a specific place on the chromosomie.

Research occurrence haplogroups allows you to track the migration of the population. In most human genetics examined haplogroup Y chromosome i mitochondrialnego DNA (mtDNA), because the Y chromosome is inherited only paternal line, but only mtDNA in maternal lines. On this basis, the calculated, when people lived, from which all modern population inherited Y chromosome and mtDNA. previously thought, that Y-chromosomalny Adam he lived about 300 thousand. years ago, a mitochondrialna Ewa about 143-200 thousand. years ago in Africa. Recent research on the oldest known haplogroup A00 require, however, move the first known male ancestor of all people over 100 thousand. years back and state, It is likely that he lived 209 thousand. years ago. It is very likely, that this coincides with the age dating of the first known human female (mitochondrial Eve) (source: https://pl.wikipedia.org/wiki/Haplogrupa)
