DNA Adventures: Me and my mum’s mtDNA – Range 16090 to 16400

In this article, I will be posting about another range sequence for my mum’s mtDNA. We have arrived at the mid-point!

You will see a summary explanatory section about mtDNA at the bottom of this article.

To my fellow Old Ninety-Six County, South Carolina cousins, this is the female line this DNA covers:

My mum < Pauline Matthews < Gertrude Harling < Aurelia Holloway < Amanda Peterson < Violet Williams < Moses Williams, Sr’s unknown first wife (not Mariah Stallsworth).

My mum’s mtDNA: Range 16090 to 16400

Genebase uses an analytical comparison measurement called RMI,which you will see in the numbers provided in the bar graph images below. RMI (Relative Match Index) is a measure of how closely your Y-DNA and mtDNA haplotype matches those of a defined population group as compared to all other population groups in the comparison. For example, a RMI of 100 means that you are 100 times more likely to belong to that population set as compared to the rest of the populatio

In the images below, Mutation = 0 is a perfect match / Mutation = 1 or more means a mutation has occurred in the comparison mtDNA matches.

  1. So…there’s quite a bit to take in. And this only covers another short range of sequence ranges for my mum’s mtDNA! Feel free to ask questions! I appreciate this takes a while to wrap one’s head around. Dorothy, are definitely not in autosomal DNA territory any more!

A quick reminder about mtDNA

Just so we all know what we’re looking at, here are some illustrations of mtDNA:

Mitochondrial DNA (mtDNA) is the small circular chromosome found inside mitochondria. These organelles found in cells have often been called the powerhouse of the cell. The mitochondria, and thus mitochondrial DNA, are passed only from mother to offspring through the egg cell

As you can see, mtDNA looks very different from the 23 chromosomes that form autosomal DNA (the DNA you inherit from both parents).

For a more in-depth understanding of mtDNA, I invite you to read Roberta Estes’s excellent article Mitochondrial DNA – Your Mom’s Story over at DNAeXplained via https://www.google.com/amp/s/dna-explained.com/2017/05/09/mitochondrial-dna-your-moms-story/amp/
