FTDNA’s chromosome browser

All in all, four establishes can be seen likewise about chromosome internet browser. These may feel chosen from the ticking boxes in one of the worst designed selectors possible. In preserving the fresh anonymity off my personal FTDNA-overall-matches and to prevent shaming the latest developer, I really don’t let you know they right here. It’s regarding 7.5 traces extreme, but shows your FTDNA-overall-fits 10 at a time, bought of the surname, requiring a vertical scrollbar. They runs with each other left away from chromosomes 8 so you’re able to 18, with plenty of empty white area left off chromosomes 19 to help you X. As opposed to demonstrating common the colour-coded place-owners where zero mugshots appear, they shows grey mugshots both for people. My personal earliest FTDNA-overall-fits by the surname is actually identified simply of the his or her initials “Letter An effective”. I must head to several other case and appear for his otherwise her the colour-coded mugshot to choose whether or not that is a masculine otherwise an excellent girls, that’s most high when examining the fresh X-chromosome.

When the Terry area-matched up me almost everywhere you to she area-matches the woman mother and this her mom region-matches me personally, i

People I know courtesy genealogy and family history sent me personally the new screenshot more than (drawn before FTDNA added this new X chromosome), generated while you are logged into the girl mom’s FTDNA kit. Why don’t we telephone call this lady Terry. There are lots much more comparable instances with the ISOGG Wiki.

Terry’s mommy and i also also are FTDNA-overall-fits. Given that discussed with the FTDNA myspace web page, we part-match towards the 14 aspects of 1cM or higher. Our very own number of common markets, longest stop shared (8.93) and complete mutual cM () merge to create all of us inside over the wonders threshold getting FTDNA-overall-fits.

Terry and i commonly FTDNA-overall-matches. Having explanations that we can come so you can afterwards, we simply cannot find in the latest FTDNA investigation how much cash, or hence locations, Terry have handed down out-of the girl mommy of autosomal DNA you to definitely their mother and i share, but we of course expect that it is about 50 %. What truly matters for now would be the fact Terry and i are located in underneath the endurance for FTDNA-overall-fits.

The newest bluish places about image over would be the 14 places from 1cM or higher on what Terry’s mom and i also area-match; the initial default visualize displayed only the 1 portion of 5cM or more about what we region-match, but there is good dropdown selection that can be used so you can reduce the threshold and you may display small places.

Having my first few days considering these types of fairly images in the chromosome internet browser, We produced the new incorrect assumption one area-matches try a great transitive family, however, this situation shows that they clearly isn’t really. age. in every the new blue markets on chromosome browser, then Terry will have to FTDNA-overall-match myself, which she will not.

Another clue which i had misunderstood something was that you to Terry’s DNA along with her mother’s DNA appear to fits during the 100% out of locations, however, i anticipate to discover Terry inherited merely 50% out of the woman DNA regarding this lady mom (you to chromosome inside for every couples), in addition to almost every other 50% (another chromosome in the for every single partners) off the girl father. The mother-child example regarding ISOGG wiki looks likewise just like the Terry’s analogy, so i know indeed there needed to be an intellectual explanation.

We looked to Bing searching for this need, and ultimately discovered a regard to 50 % of-identical regions. Believing that I might get on the best song, We googled you to phrase, which introduced us to Example nine of your Beginners Self-help guide to Genetic Genealogy and family history towards Wheaton Surname Information website, at which phase a light-bulb eventually ran out-of in my lead! I am hoping I’ve explained the idea of half of-identical area certainly above.
