Autosomal sibling test?

[tomcat]

Isn't it true that the X test reveals the father's maternal line? In a situation like burto's mom and my mom who don't know anything about their fathers, could we get a clue about their father's ancestry that way? I know that my mom shares some X markers in common with someone else whose ancestor is from the same area as her father.

Your mother's X contains contribution from both her mother and her father. Her father's X contribution comes directly from his mother. And although that inheritance was conserved in him (because he had but one X and so could not recombine X) the X he got was a recombined product of his mother's two X's. And so that X also contains signatures of both of his mother's parents.

There does seem to be a bit of pattern across 10067 and 10068.

For example if you enter 13 for 10067 you will find 4 with 22 at 10068. If you enter 14 at 10067 you will find 5 with 21 at 10068. If you enter 15 at 10067 you find a high incidence of 21 at 10068. And if you enter 16 at 10067 that 20 and 21 occur about equally at 10068.

I don't see these correspondences carrying over to 10066 or 10069.

I do see that..I think Thomas Krahn told me that..
what I am wondering is..does that pair of markers..say 15(10067) and 21 (10068) do they travel along with the 10074 triad? or could they be inherited as a pair separately.. to show traits of 2 different families..
Is that a stretch?

Well anyway I have my sister's in being tested now..those 4 10067/68/69/66

Slowly but surely..

You could test that on Xmatch by comparing common motifs on 10067,68 and 10074,75,79.

I don't know what to make of it as among my siblings 10067,68 do recombine ...

Your aunt's daughter's maternal X is a recombined product of your aunt's X's. All potential information about your aunt's maternal X is available in your aunt's X results. You add nothing by testing her daughter.

Hi,
So if my Mum and Aunts haploblocks were different then it's a waste of time? Maybe if we just did Mum's and put them in a database some relatives may come up! I've inheirited this fascination of family history from somewhere, maybe it's in my Grandpa's genes!!!
I can hope

You don't know the haplobocks are different.

And will not be able to tell one haploblock from another without a succesful comparative test of your aunt.

So, your mother's results might come back as 12,14 and 13,15 and 16,17 but you could not know whether one block was 12,13,16 or 12,15,17 or 12,13,17 or 12,15,16 and neither could any of those who were searching the database on which you were posted.

Unfortunately most of the postings on Xmatch from females testees are undifferentiated in that regard. So, while one might match them generally there is no way of knowing if one matches them specifically or to which of their lines one does match.

And that is why the haploblock that I have been able to compare of mine which is different from my Sister's is significant...
between she & I we are able to show this:
Dad's Haploblock: 15,16,16
Mom's #1 Haploblock 17,17,19
Mom's #2 Haploblock 8,18,18

I am going to test my Female cousin in the hopes that she will match one of Mom's haploblocks ..that may make it more specific which family line that it is from..
her brother ( My male cousin) Would only have the one X marker from his Mom ( Not related to me)
I am testing him so I know which haploblock is their Mother's..( She is Irish too)
Since Male Cousin has already tested here it is neglibale to do his 3 markers..
Female Cousin is another story..at $110 I think..they have siblings also but maybe I won't have to go there..
