Introduction

J mtDNA Migration - From National Genographic

This blog is about Mitochondrial DNA Haplogroup J. Everyone has Mitochondria within their cells that convert energy from food into a form we can use. Each cell contains hundreds to thousands of mitochondria.

MtDNA is passed from mother to child. Males do not pass their mtDNA on to their children.

On occasion there are slight mutations. These changes are then passed on to children. These mutations allow us to trace our ancestry back in time on the maternal line. The changes enable you to identify your genetic mtDNA "cousins".

Haplogroup J descends from the haplogroup JT. In his book The Seven Daughters of Eve, Professor Bryan Sykes named the originator of this mtDNA haplogroup Jasmine.

    Editors Note -This blog is intended to integrate what we know about J mtDNA in one place. There are a number of sites that cover J mtDNA including two Facebook pages and a Yahoo page. They are excellent discussion pages but you get lost in the forest for the trees. Wikapedia and Eupedia provide interesting information. Other sites are buy profit companies, two of which have gone out of business with some loss of information.  We try to copy some of that info here without incurring the copyright wrath of the companies.
