Today, everyone wants to use DNA tests for a number of reasons. The most common reason is to find living relatives but according to geneology4u, there are other folks out there who are less interested in connecting with long-lost relatives than they are about exploring their distant roots and cultures.
What it requires?
Discovering your deep ancestry requires looking at your ancestry from a different angle and modern DNA testing is making new and exciting advances all the time. Geneology4u explained many aspects of genes in detail, including two types of DNA called “STRs” and “SNPs”. STRs are used for modern relative finding and matching purposes, where SNPs, (single nucleotide polymorphisms) are used for tracking ancestral migrations and exploring deep ancestral information, such as haplo groups.
A haplogroup is basically a grouping of people that share a common bloodline and are connected to a specific family line often dating back many thousands of years. We personally believe the oldest known humans originated from eastern Africa and from there they spread throughout the world. Different mutations occurred in the geneology4u and distinct differences began to emerge setting the groups apart from one another. Commonly studied are the Y-chromosome genes and the mitochondrial genes. Y-chromosome gene follows the male (patrilineal) line, from father to father to father. The mitochondrial gene follows the female (matrilineal) line but is passed to both sexes, male and female. All children receive mitochondrial gene from their mothers only.
What about exploring the regions of your bloodline?
Geneology4u offers a My Origins feature with their Family Finder (autosomal) DNA test. The results from this test by geneology4u provide a breakdown in the form of a percentage of the genetic populations (regions) to which your particular DNA is connected.
Why it is important?
It’s important to remember that while deep ancestry is taking great strides and providing us with exciting information, the science is still young and evolving. Geneolgy4u reminded those attending his presentation that “each company has its own set of reference populations or reference panels. So there’s going to be differences in just the markers alone, and then there’s going to be differences in the algorithms that each company uses to analyze that. So it’s not that the results are wrong, or that one test is better than another. It’s that we’re still working on what works, what doesn’t work, [and] how we can improve it. It’s only going to get better, and it’s only going to get more accurate. This is something really important for the ones who are discovering to learning more about their family genealogy.
