Different genetic relation strength through maternal vs paternal line?

You inherit exactly half your DNA from each parent. So, no, you are not more related to one parent or the other. However, it is unlikely for you to inherit exactly a quarter of each of your ...

My Full DNA: Whole Genome Sequencing with mtDNA from dante labs

The difference between a DNA test for genealogy and a WGS (Whole Genome Sequencing) test is that the test for genealogy obtains values for about 700,000 SNPs (Single Nuleotide Polymorphisms), whereas ...

Why doesn't the haplogroup K2b2 appear on MitoSearch.org?

The thing to realize is that DNA science is new and quickly evolving as more people test and the science gets better and more granular. As such it was identified a couple years ago that Haplogroups ...

Is there value in doing an mtDNA for a first cousin once removed?

The only real reason for doing an mtDNA test for genealogical purposes is to prove that one person's female line connects with another person's female line. However, mtDNA is passed down almost ...

Finding others with H2a1 maternal DNA?

Yes, you've got the right idea. mtDNA is passed identically from generation to generation with only an occasional mutation every so often. In your case, going up 1000 years and down again 1000 years, ...

Seeking the mtDNA raw data or actual results for the Windover Bog Site Mummies
