ROH Endogamy Detector

[Isinimo]

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.

[J. Ketch]

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.
