ROH Endogamy Detector

[Kostek]

Has anyone scored significant precent on the ROH Endogamy Detector on Exploreyourdna? I score 0% but my grandfather scores 5.88%, that's more than Ashkenazi Jews, Druze and Romani. All of his great great grandparents were from the same village so I guess it makes sence but I didn't expect such a high score!

My results. I have no Romani ancestry.

[Beowulf]

My paternal grandpa scored more than 5%

And you?

[RareNightmare]

I scored high Endogamy but my parents aren't related. They're 2 different ethnicities. I'm sure that their recent ancestry is inbred tho

Strong endogamy — Regionally isolated population.
FROH = 2.58% · SROH = 74 Mb · 29 segments · Longest: 16.3 Mb. Level comparable to Ashkenazi, Druze or Bedouin populations.

From what I remember I had around 15.69 total ROH mbs, that's lower than some heterogenous (ex. West Central Africans) populations.

[Graham]

Above Basque and Finns, similar to Sardinians.

Moderate endogamy — Regionally distinct ancestry.
FROH = 1.39% · SROH = 40 Mb · 27 segments · Longest: 5.2 Mb. Comparable to Finnish, Sardinian or Basque populations.

[Birchy]

Low endogamy — Outbred population.
FROH = 0.00% · SROH = 0 Mb · 0 segments · Longest: 0.0 Mb. No significant endogamy signal. Normal range for non-isolated populations.

[ScandinavianCelt]

Using my merged file:

Strong endogamy — Regionally isolated population.
FROH = 3.32% · SROH = 96 Mb · 29 segments · Longest: 23.7 Mb.

Level comparable to Ashkenazi, Druze or Bedouin populations.


Using 23andMe only:

Strong endogamy — Regionally isolated population.
FROH = 4.16% · SROH = 120 Mb · 38 segments · Longest: 24.0 Mb.

Level comparable to Ashkenazi, Druze or Bedouin populations.


In both cases mine shows a large piece on chromosome 1, but it's exactly my centromeres section, and it carries hard-to-read SNP markers, so very little usable SNPs. When I try to isolate these segments with Admix Studio app I see the calculators do not run because not enough SNPs to measure these. Exploreyourdna says otherwise, but I can't measure these segments on my own to show anything meaningful. For example, chromosome 1 shows Amerindian, Omotic, and West Caucasian.

I'm not sure this calc is of any value.

Low endogamy — Outbred population.
FROH = 0.00% · SROH = 0 Mb · 0 segments · Longest: 0.0 Mb. No significant endogamy signal. Normal range for non-isolated populations.

I feel like a complete inbred compared to most of you. How to reverse the effect? :cool:

[Vessna]

Very strong endogamy — Isolated population signature.
FROH = 5.21% · SROH = 150 Mb · 51 segments · Longest: 24.5 Mb. Your profile matches isolated populations like Romani or tightly closed religious communities.

I obviously do not have Romani ancestry. These results are a “forest-zone isolate signal” which is a pattern in populations whose ancestors lived for centuries in the northern East-European forest belt roughly the area stretching across Lithuania, Belarus, northern Poland and parts of western Russia. These regions historically had dense forests and scattered villages which created semi-isolated micro-populations.

Interesting! Can you also check for your husband?

The GedMatch ROH Are Your Parents Related? tool seems to have fewer people counted as consanguineous.

According to that tool my paternal grandparents are distantly related:

The contradictions among the results for my three data sets are dissatisfactory. They question whether this specific procedure is reliable. For whatever reason it says zero SNPs parsed from my FTDNA raw data. Seemingly it can not be read. This doesn't change, whether I use the zipped or unzipped data. But in the merged data the FTDNA data is integrated in a readable manner. There are over 1.1 million SNPs parsed.

You can by chance have your parents a little bit related and then you get a result that you can not project onto your population. On the other hand too many here seem to get too high results.

Zero SNPs parsed. FTDNA raw data?

[Tilaratch]

Help now I'm scared

According to the GEDmatch tool your parents are not related, so don’t worry:

No shared DNA segments found

Their families are from different parts of Sweden anyways

[villainchai]

Everyone including myself is getting ridiculously high scores so I am assuming this tool is broken or retarded.

I mean technically I guess I could be slightly inbred since just under 3/4 of my heritage all comes from the same tiny radius as far as I know, going back to the 1400's ish.

But like, come on. We can't all be Bedouin level inbred

Very similar result.

[Boudin]

The two 23ande results are 2% more inbred than the three Nebula results. I think 23andMe results aren't representative of the entire genome for this purpose.
