Autosomal sibling test?

[Kathleen Carrow]

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..

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.

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.

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?

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 ...

[Kathleen Carrow]

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

Slowly but surely..

[Kathleen Carrow]

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.

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.

Hi,
My Gran died and she was an only child-that's why I wondered if getting my Aunts daughter tested might help as surely she would get the same X as her Mum and ultimately that would help us determine which X was from my Mum and Aunts mother?

Always best to test as far back up the lines as possible! If you test descendants you are just adding more unknowns to the problem. Find and/or convince famly to test. The DNA of family elders is IRREPLACEABLE ... they may be flattered.

...
I THINK that the DXS10067,10068,10069 is also supposed to be slightly informative..
I forget where I heard that tho'

What about my Aunt's daughter? Or me? That's about it really...don't know Mum's Dad or his family and her Mum's family don't talk

So if Mum buys the test, does that mean my Aunt and cousin would get it cheaper ir do they have to pay full price too?

NO! it is only cheaper if your sample is already at Family Tree DNA..
I tested my one cousin and my Sister..so when I do my Sister's X Markers it is $8.68 per marker but of course it is not that cheap if your sample is not there..

Do you have any of your family who have their sample here? Who tested here? THEY would be cheaper if you tested their X markers..you do NOT have to test the whole Panel..

I will have to pay $110 to test my female cousin's panel..

In the meantime I am finishing up my sister's X markers..3-4 at a time..
her markers compared to mine will give me my Dad's entire profile..
which is my paternal grandmother's family..also mostly Irish..even tho' it is my Colonial America line also..

IF you tested your Mom and her sister..if they had a haploblock in common..the OTHER 3 markers of your Mom could be compared against a known relative of HER father..your biological grandfather( at least I think that is correct ).. is he known to you?
My biological Paternal GF is NOT known to me..
