I want to purchase DNA testing & get results for both my maternal & paternal lines. I'm looking at the Y-DNA37+mtDNAPlus test. My brother will take the test for me.  Can I take the maternal test or does my brother have to take the entire test for me.  And,  is this the best test from Geni to take? I haven't found where I can submit a direct question to Geni. Thank you for you help!
