Saturday,

25% shared). Circumstances #1 For a few months, I have already been working with a lady who had been given up because a baby. We’d properly zeroed for the for her biological relatives compliment of pedigree triangulation into this article the AncestryDNA and you will was basically trying determine which out-of a couple of sisters was the lady biological mother. The new daughter of just one of the sisters got accessible to sample at MyHeritage, with the expectation off a DNA show consistent with both earliest cousins otherwise half of-siblings. The lady show came back which have 17.9% (step one,294.nine cM) DNA mutual between the two. This was unfortunate because it dropped from inside the a gray area where brand new selections from mutual DNA with the several you can dating overlap, which looked like we could possibly haven’t any decisive cure for practical question off the girl parentage. I up coming posted the lady investigation so you’re able to Gedmatch and you can was indeed astonished in order to observe that they actually shared

Will not FTDNA manage MyHeritage’s research performs? This feels like either a flawed formula or perhaps the accessibility different default thresholds (age.grams. eight cm vs ten cm). I really hope they define so it eg last night. We need to strive for consistancy, maybe not confusion.

It is possible which they utilize the same or identical equipment to find the data, but perform the data alone. Bear in mind that brand new cM “distance” is actually by itself an offer according to the empirically-derived recombination prices with each other per chromosome. A difference for the patterns, a change inside the thresholds, a distinction when you look at the mismatch focus on-size limitation, normally the change the computed cM beliefs, given the same raw studies.

Having surface, the fresh new comparison enterprises would need to agree on plenty variables. However, it consider the factor options proprietary–the fresh “magic sauce” one distinguishes the services they offer.

I do not envision any of us anticipate the companies to statement exactly the same number, however it shall be close. In the event it isn’t really, they leaves to your matter the basis your entire industry.

Myheritage really does explore FTDNA’s lab in order to techniques the fresh new DNA, even so they play with her formulas to help you writeup on coordinating. What exactly is interesting in my situation in these advice is that myheritage accounts faster DNA than just in the gedmatch. Regarding the alot more faraway relationships the problem is that they declaration too much common DNA (believed are due to imputation). I might feel extremely curious to find out if a comparable show are present getting set transferred to myheritage (I’m if the newest reviews at this point is for all of us just who checked out from the myheritage?)I’m not sure getting this respond to reveal my term!!

My brother and that i both published to my Society. We express 158cM with the Gedmatch and you can 133cM toward Ancestry. We have never ever shown on for each other people’s matches listing on the My personal Heritage.

My personal estimate using my full sis is even most straight down for the My personal Customs than simply Ancestry and Gedmatch. To my Lifestyle, they inform you we share 1328cM against a great 1709cM express to your Gedmatch and you may 1641cM for the Ancestry.

My personal brother: Origins 2453 cMs more 60 locations, FTDNA 2401, GedMatch 2575, MyHeritage 2279 more than 37 places. All of the towns other than MyHeritage believes this is certainly my personal complete cousin. MyHeritage believes this is possibly a 1 / 2 cousin, buddy otherwise full aunt.

I see similar results with my match to my 1/2 brother.At Ancestry, we match at 1681 cM. Upload to GEDMatch shows 1728.9 cM, and a Family Tree DNA transfer shows 1651 cM (ignoring segments <7 cM and shared X yields cM).
