My Nephew Avi

My nephew Avi's Family Finder results just came in. Avi's mother - my sister Carol/Devorah - was killed in an auto accident thirty years ago. But she and Judith are identical twins so we have her DNA. Except for the astigmatism and later the glasses, you could not tell them apart.

But Judith wanted to know what the DNA would say so we ordered Family Finder tests for Avi and for one of Judith's sons Eliezer. Eliezer's was delayed in the mail - or in FTDNA's mail room - but should be along in two or three weeks.

These are Avi's matches with his mother's six siblings.
FTDNA accepts him as Judith's son, as expected.

When I looked at the six of us against one another a few months ago, I saw that Amy is not as close to Judith as the rest of us. This shows up in Avi's match with Amy as well, both in the longest segment and in the total.

Avi's match with Judith is 3382 cM.

We have five other Pikholz parent-child comparisons: Aunt Betty and her son, Uncle Bob and his daughter, my fourth cousin Nan and her son and daughter and Maxine from the Nachman Pikholz line and her daughter. Aunt Betty's son, Uncle Bob's daughter and Nan's daughter share 3384 cM with their parent. Maxine and her daughter share 3383 cM and Nan and her son share 3382 cM. All five and Avi have a longest segment of 267 cM.

On Avi's chromosome browser, I see tiny breaks in chromosomes 3 and 8, so I assume that is what is missing from the 3384. In any case, this layman doesn't see anything that implies anything special about the twins.

After I get Avi on GEDmatch and see Eliezer's results, I'll have another look.
