Like mt DNA, these mutations can be grouped and categorized into haplogroups.
The y-chromosome of Anzick-1 was sequenced, and researchers determined that his y-chromosome haplogroup is Q-L54*(x M3), one of the major founding lineages of the Americas.
They sequenced the mitochondrial DNA (mt DNA), the full nuclear DNA, and the Y-chromosome, and compared these sequences to those of modern populations throughout the world.

The mitochondria is maternally inherited by all persons, and analysis of the mt DNA can provide information about maternal ancestry. They found that Anzick-1's mt DNA belongs to the haplogroup D4h3a, a "founder" haplogroup that might represent people taking an early coastal migration route into the Americas.
Although it is rare in most of today's Native Americans in the US and Canada, D4h3a genes are more common in native people of South America.
Another line may have moved inland, east of the Rocky Mountains, ultimately populating most of what is now the United States and Canada.
The y-chromosome is inherited directly through the paternal line from father to son in each generation.
This suggests a greater genetic complexity among Native Americans than previously thought, including an early divergence in the genetic lineage some 13,000 years ago.
One theory suggested that after crossing into North America from Siberia, a group of the first Americans, with the lineage D4h3a, moved south along the Pacific coast and finally, through thousands of years, into Central and South America.Anzick-1's genome was closer to 44 Native American populations from Central and South America than with 7 Native American populations from North America; samples from North America were limited as tribes in the United States have been reluctant to participate.Mt DNA is DNA located in mitochondria, an organelle that is found in human cells. sequenced the mitochondrial DNA of Anzick-1 and determined that the infant represents an ancient migration to North America from Siberia.These analyses revealed that the individual was closely related to Native Americans in Central and South America, instead of being closely related to the people of the Canadian Arctic, as had previously been thought likely.(The people of the Arctic are distinct from Native Americans to the south, including in lower North America and Central and South America.) The infant was also related to persons from Siberia and Central Asia, believed to be the ancestral population of indigenous peoples in the Americas.The site contained hundreds of stone projectile points, blades, and bifaces, as well as the remains of two juveniles.Tags: Adult Dating, affair dating, sex dating
