Just to illustrate regarding precisely what the FTDNA chromosome web browser looks like when you compare brand new logged-in the system to a couple of almost every other establishes:

FTDNA’s chromosome internet browser

A total of five set can be viewed at the same time regarding the chromosome web browser. These may getting selected of the ticking boxes within the terrible tailored selectors imaginable. To preserve the privacy from my personal FTDNA-overall-suits and end shaming the fresh new designer, I do not reveal they right here. It is about 7.5 outlines tall, however, suggests a person’s FTDNA-overall-suits 10 at the same time, ordered by the surname, necessitating a vertical scrollbar. It runs together left regarding chromosomes 8 so you’re able to 18, with lots of blank white room to the left off chromosomes 19 to help you X. In place of showing plain old colour-coded place-people where zero mugshots arrive, they suggests gray mugshots for males and females. My earliest FTDNA-overall-suits by surname are identified merely because of the their unique initials “N An effective”. I need to visit another case and appear for his or this lady the color-coded mugshot to determine if or not this might be a male or an effective ladies, which is really high when considering the newest X chromosome.

If Terry part-matched up me personally every-where you to she region-fits this lady mom and that the girl mommy region-matches me, i

Some one I am aware compliment of genealogy delivered myself the fresh new screenshot more than (taken ahead of FTDNA added the latest X chromosome), made whenever you are signed directly into the woman mother’s FTDNA kit. Let us name their Terry. There are plenty a whole lot more equivalent instances on ISOGG Wiki.

Terry’s mom and that i are FTDNA-overall-matches. Since chatted about on the FTDNA myspace web page, we region-suits into the fourteen regions of 1cM or even more. Our quantity of common areas, longest stop common (8.93) and full shared cM () merge to carry united states inside above the wonders threshold to possess FTDNA-overall-fits.

Terry and i also aren’t FTDNA-overall-matches. To have reasons which i will come to help you afterwards, we cannot get in the FTDNA studies how much, otherwise hence markets, Terry has actually passed on of the woman mommy of your own autosomal DNA you to their mother and that i express, however, i definitely expect it to be approximately half. What counts for now is the fact Terry and i also are located in beneath the tolerance getting FTDNA-overall-suits.

The blue regions from the visualize over could be the 14 avenues of 1cM or higher about what Terry’s mom and i also area-match; the first standard visualize showed just the step 1 part out of 5cM or higher about what we region-suits, but there is however a great dropdown selection which you can use in order to reduce the threshold and screen the smaller regions.

To own my personal first few days deciding on these quite pictures about chromosome browser, I made the incorrect presumption that part-matches is actually an excellent transitive family relations, however, this example means that they certainly isn’t really. e. in every the new blue segments regarding chromosome internet browser, following Terry will have to FTDNA-overall-meets me personally, and that she doesn’t.

The next clue which i had misinterpreted something is the reality that you to definitely Terry’s DNA along with her mother’s DNA apparently meets in 100% out-of towns, but we anticipate gratis BBW Dating to discover that Terry inherited simply 50% out-of their DNA of the girl mom (you to chromosome for the each couples), and also the almost every other fifty% (others chromosome inside the per couples) regarding the girl father. Brand new mother-kid analogy on ISOGG wiki seems likewise as the Terry’s analogy, therefore i understood truth be told there must be a rational explanation.

I turned to Google interested in this factor, and in the end located a mention of 50 % of-identical countries. Thinking that I would personally be on suitable song, We googled that keywords, which introduced us to Concept nine of one’s Beginners Help guide to Genetic Family history into the Wheaton Surname Info webpages, of which phase a light-light bulb ultimately went from during my direct! I hope We have said the idea of 50 % of-identical region demonstrably over.
