mtDNA / Y chromosome pedigree, animated image
Studies following the male lineage (using the Y chromosome) have been compared to studies following the female lineage (using mitochondrial DNA (mtDNA)). The results suggest that men and women have had different roles in the peopling of the planet and in the mixing of genes among population groups.

Geneticist Jaume Bertranpetit speaks about the findings from Y-chromosome and mtDNA studies.
This illustration shows the two major mitochondrial DNA lineages. The lower branch includes only African populations. The upper branch has both African and non-African members.
Geneticist Michael Hammer speaks about Y-chromosome studies used to correlate a population's tradition with its genetics.
Unlike nuclear DNA, mtDNA is Â inherited solely from the mother. (Mitochondria are predominantly from the motherâs egg and not from the fatherâs sperm.) Therefore, mtDNA sequences or orders of nucleotides generally remain constant over many generation
Molecular geneticist Douglas Wallace talks about the way mitochondrial DNA is inherited.
Human mitochondrial DNA is 16,569 base pairs in length.
Author Steve Olson talks about the possibilities for new genetic data about the history of human populations.
Evolutionary geneticist Michael Hammer talks about tracing modern Y chromosomes back to a common ancestor.
DNA found in the mitochondrion of a cell differs in structure and is separate from the DNA found in the cell nucleus. Mitochondrial DNA, or mtDNA, exists as a circular loop of double-stranded DNA rather than the linear form found in nuclear DNA. However,
