re: Anyone used ancestry.com?

Ancesrtry worked better for me , 23 and me has something unique that can test dna with medical tenancies and give you results . I was more interested in my family tree . Google , my heritage and the library can also be helpful . The way autosomal dna is created or passed down is not mathematical as you can have dominated genes . A sibling that isn't an a twin may have a different amount of one ancestor than than their sibling .
