Unfortunately, there is no “rule of thumb” for mitochondrial DNA genetic distance relative to years and generations distant. In other words, there is noTIP calculatorfor mtDNA. I did some research some years ago attempting to quantify MRCA (most recent common ancestor) time and answer this ve...
Y DNA ResourcesCategory Archives: Chromosome Mapping Six Ways to Figure Out How We’re Related Posted on September 9, 2024 5 In my latest Webinar, Six Ways to Figure Out How We’re Related, I discuss the various tools from Ancestry, FamilyTreeDNA, MyHeritage, and 23andMe –plus cluster...
One of the very early studies based on the Y-chromosome and a few autosomal markers, which included almost all the main SEB groups and covered most of the provinces from South Africa, indicated the possibility of genetic structure within the SEB populations29. However, many subsequent studies ...

Schistosomiasis is a neglected tropical disease that afflicts millions of people worldwide; it is caused by Schistosoma, the only dioecious flukes with ZW systems. Schistosoma japonicum is endemic to Asia; the Z chromosome of S. japonicum comprises one-q
We tested ∼5.5 million common genetic variants (MAF > 0.01), including those on the X chromosome, in six case control studies from Europe and the United States totalling 1556 cases and 7100 controls, all of European ancestry (Supplementary TableS1). Individual studies were adjusted for ...
Here we perform a de novo chromosome-level genome assembly of the wild progenitor of castor bean. By resequencing and analyzing 505 worldwide accessions, we reveal that the accessions from East Africa are the extant wild progenitors of castor bean, and the domestication occurs ~ 3200 years ...
The blaOXA−48 variants mainly existed on chromosome and share a conserved genetic environment like endA-sprT-orf- blaOXA−48-lysR-accA, except for strain GCA_023476085, in which two ISSheS2 were found in the downstream of blaOXA−48. Among 18 genomes, one to five sul1 gene were ...
X-DNA has a very unique inheritance pattern because males only inherit an X chromosome from their mother which limits the number of potential common ancestors for any two testers. In other words, X-DNA matching does half your work for you!
This female and male full sibling match can’t share an X chromosome on the father’s side, because the male’s father doesn’t contribute an X chromosome to him. The son, Henry, inherited a Y chromosome instead from his father, which is what made them males. ...
