    Mine is 29.60. I wonder what the American average is...

    And yet the parents of one of my great-grandmothers were second cousins and her maternal grandparents were also second cousins. Three out of her four grandparents were first or second cousins to each other. There were other second cousin marriages further back in her family tree, and she descended from some of her ancestors by eight or nine different lines.

    On the other hand, in spite of one inbred great-grandmother, my ancestors of four or five generations back were quite ethnically diverse and widely scattered. They covered five different nations, two continents, six islands and two hemispheres. Even those in the same country were generally from different places within that country. So, given the limited opportunities for interbreeding for many of them, it's not surprising my score is below the European average.

    I have an almost fully complete family tree dating back to the early 17th century, and most of my ancestors were from a small cluster of tiny villages in the mountains. I also have a few 18th century nobles that seemed to like marrying one another, so I am guessing this number is higher than average.

    Hi, how are you?


    Have you done the Yfull?

    -----------------------

    Does it take that long for me to get nothing?

    Not sure what that is...I'm new to all of this.

    You have to get the BigY 700 and when you have it you load it in Yfull otherwise we do nothing, we can continue talking 1000 years more than anything.

    People whose parents are related in some way may find some lengthy ROHs in their own DNA. As an example, the following ROHs were found on five different chromosomes of a person whose parents were first cousins (this example uses the utility's default settings and is based on FTDNA's Illumina chip):

    • 11719 consecutive tested SNPs, corresponding to a DNA segment of length 52.72 Mb.
    • 7429 consecutive tested SNPs, corresponding to a DNA segment of length 39.04 Mb.
    • 6468 consecutive tested SNPs, corresponding to a DNA segment of length 28.96 Mb.
    • 5593 consecutive tested SNPs, corresponding to a DNA segment of length 27.70 Mb.
    • 6060 consecutive tested SNPs, corresponding to a DNA segment of length 22.90 Mb.

    The full collection of detected ROHs account for 11.384% of the reported genome for this person.

    This is what appears on the screen, I don't know if it's an explanation or my results.

    Hi Carlos.

    It's an explanation. See at https://www.math.mun.ca/~dapike/FF23utils/roh.php

    Cheers :)

    Yes, it is the same one that is in the first post but it doesn't work for me or it takes a long time so I tried it with Gedmatch

    GEDmatch - Are your parents related?

    Largest segment = 0.0 cM
    Total of segments > 7 cM = 0.0 cM

    No shared DNA segments found

    No indication that your parents are related.

    This discussion on very long ROH on reddit was also pretty interesting on that subject:
    https://www.reddit.com/r/ClinicalGen...ic_phenomenon/
    I wonder if anyone here have uniparental disomy

    I have a doubt for many years. I did some studies and my teacher was a Belgian old and long-distance, someone really cultured and had even worked for Hollywood. The first day of class I arrived last, I crossed the whole room until I reached the room where classes would be taught when the door was opened, everyone was already there, the teacher behind his desk and the rest of the students sitting in their chairs, so in record time I occupied the first empty chair I saw and just as I sat down the teacher said: Another hybrid!


    That stayed in my mind but in the following years I never asked him what he meant by that. In the class we were all Spaniards, except an Argentinian with a Galician father, a German mother and a boy with a Catalan father and a Dutch mother, I don't know if it can be related in that sense and in this factor I have fallen relatively recently since they passed me by the head another type of themes.


    I don't know how you see it.
