FTDNA’s chromosome browser

All in all, five set can be viewed simultaneously from the chromosome browser. These can be picked from the ticking boxes within the poor designed selectors imaginable. In preserving the new privacy regarding my personal FTDNA-overall-fits in order to stop shaming the fresh new designer, I really don’t tell you it right here. It is about eight.5 traces significant, but reveals a person’s FTDNA-overall-suits ten at the same time, ordered from the surname, necessitating a straight scrollbar. It runs along left away from chromosomes 8 so you’re able to 18, with a lot of empty light area to the left of chromosomes 19 so you’re able to X. In lieu of appearing common the color-coded place-proprietors in which zero mugshots appear, they suggests gray mugshots for both gents and ladies. My very first FTDNA-overall-fits from the surname is identified just of the his or her initials «Letter An excellent». I need to head to other tab and appear to possess his or the lady colour-coded mugshot to determine if this is certainly a male or an effective females, which is very extreme when looking at the brand new X-chromosome.

In the event that Terry region-matched up myself everywhere that she area-suits the girl mommy and therefore the woman mother region-fits me personally, we

Someone I understand as a result of genealogy and family history delivered myself the fresh new screenshot significantly more than (removed in advance of FTDNA extra the newest X-chromosome), generated if you are signed directly into the woman mother’s FTDNA kit. Let us call their Terry. There are lots far more comparable advice toward ISOGG Wiki.

Terry’s mommy and that i are also FTDNA-overall-suits. As the talked about toward FTDNA twitter webpage, we region-match towards 14 areas of 1cM or more. Our very own number of shared avenues, longest block common (8.93) and you may full mutual cM () combine to bring you in the over the wonders endurance to have FTDNA-overall-fits.

Terry and i also are not FTDNA-overall-matches. Having factors that we can come to after, we cannot find in new FTDNA analysis simply how much, otherwise which locations, Terry enjoys passed on regarding their mother of your autosomal DNA that this lady mother and i also express, but we of course predict it to be approximately half. What matters for now would be the fact Terry and i come in below the threshold for FTDNA-overall-fits.

The fresh new blue places on the visualize significantly more than are definitely the fourteen locations from 1cM or even more on which Terry’s mother and i part-match; the original standard picture exhibited just the step 1 segment of 5cM or even more on which i region-suits, but there is an excellent dropdown eating plan which can be used so you’re able to reduce the endurance and you will screen the smaller nations.

Getting my personal first few days thinking about such very photographs regarding chromosome web browser, I produced the incorrect presumption one part-suits is an excellent transitive relation, but this case means that they rimorchiare adulti demonstrably is not. elizabeth. throughout the latest blue markets in the chromosome browser, up coming Terry will have to FTDNA-overall-matches me, and that she does not.

The next idea that i had misunderstood anything try the point that you to definitely Terry’s DNA and her mother’s DNA apparently fits within the 100% regarding cities, however, we anticipate to realize that Terry inherited only 50% out of the girl DNA from the girl mommy (that chromosome from inside the each pair), in addition to almost every other fifty% (one other chromosome within the for every few) from the woman father. The fresh mother-son analogy throughout the ISOGG wiki looks just the same since Terry’s analogy, so i realized here needed to be an intellectual reason.

We looked to Yahoo trying to find so it need, and finally discover a mention of the 50 % of-identical regions. Thinking that I would personally be on the best tune, I googled you to phrase, hence produced us to Training 9 of the Newbies Help guide to Hereditary Genealogy and family history to your Wheaton Surname Information webpages, where stage a light-light bulb fundamentally went out of in my own head! I am hoping We have said the concept of half of-the same region certainly above.
