ySTR Counts

[AJAskey]

As I understand the dynamic nature of calls on some SNPs, it has to do with the original reference sample. Some of the reference "base" calls were actually mutations. It will take time and a larger population of samples to determine the true reference base for all locations. You may be positive...

I don't know what YFull does but I assume it is all software reading the file(s). There is no reason that the whole thing cannot be automated. Any "judgement" calls must follow some rules which can be added to the software algorithms.

If humans are reviewing the results...

Chere - One thing to keep in mind is that you will continue to learn over the years. There is no rush to know everything in the next month. Testing is relatively new and what we "know" now may be different than what we "know" in a few years.

Thank you for the link. It is very interesting information....

Nathan - Thanks again for the links. I have seen the diagram but have not read the article. What I really want may not be available due to lack of data as of today. If this were my field, I would research the information when a mutation does occur.

Thanks Nathan. I reread the FAQ and still did not see the answer to my question. But it may be in there and I missed it. I'll take your answer unless someone tells me different. I would think someone would have done a statistical study on counts between known close generations. If I find one online...

Is it possible for a son to have a lower count for a marker than a father or grandfather? For example, one father has a DYS456 of 16 while the son has a 15. Is this possible? Rare? Can't happen?

Are there any rules for STR counts? General guidelines? I just need an expert or links to information...

Haplogroups

I have found that determining a high resolution on a haplogroup makes everything much easier. I am in Haplogroup U152 at this time and hoping to resolve this even deeper. This may or may not match my historic paper trail into Scotland. In in any case, I have no need to...

[AJAskey]

Phil - what is your ySearch id? I can't believe you don't match anyone with that Haplogroup. If you post your id I can search using your markers.

[AJAskey]

If everyone got yDNA tests, then it would be easy. For example, I am doubting whether paper ancestors from the late 1600s are related to me based on DNA. But I have a match to a cousin who connects to my tree in 1727. From that point forward, he and I can be reasonably confident that our paper trail...

I have a feeling (based on the name matches I am getting) that most people are not who they believe they are. It only takes one infidelity on the paternal side over the last 500-1000 years to put ones Y markers anywhere but where one believes. The only way to "know" is for many of your recent...
