Forgive me I forgot.
Do not, Do not test on your own.
I and my GD - 10 tested our own design Z253 pack (Z253 arose around 1734 BC) before the experts put these packages together, and at a much greater cost.
There is a Z253 pack offered by FTDNA.
I don't mean to sell anyone anything.
I just want to share what I know about deep clade testing.
We've all seen prices go down and they will continue to do that.
Contact me off line before you even consider a Z253 bundle or anything and I'll be sure to get an Admin to advise us.
If you buy the BigY, I'll consider you can afford it.
Nevertheless, if you do, expect me to sponsor a backbone test for a GD of 5-6 of yours, while the sale lasts.
If not I'll make a contribution to the McClure Project Fund.
