G1a2 maternal halogropu match or partial match?

i am G1a2a

It isn't a good idea to look at maternal/paternal haplogroups if you are searching for close relatives, as there are usually thousands or even millions of people fall in the same group. Autosomal segment matches within 3 generations are mostly reliable, try Gedmatch one-to-many matches or "基因关系" in WEGENE.

I'm a adopted kid too.  How can it find ur relatives? Is that work in wegene? Or just 23andme?
 
And ,anyway ,hope you can get what's u looking for .
