Re: Who is the better option for DNA: siblings or father and son? #dna

My dad did a dna test and I'm always seeing ads for an even more extensive test.  Does he need to get tested again if I pay more?  Or do they use his same sample and just test more strands etc?  Is it worth it to get an even more extensive test?  Thank you,
