Before you shell out big bucks for a population DNA test, trying to determine your ethnicity, be very aware. Costing more or less is not your best guide to their effectiveness. Both 23andMe and Family finder at Family Tree DNA of Houston use exactly the same chip. It tests over 700,000 markers and is the best on the market. 23andMe has lagged a bit behind but should be making some big changes very soon in drilling down into your ancestry. Family Finder is already doing this.
Population Finder
Reveals Ethnic Ancestry
Population Finder is a report included with the Family Finder DNA
test from Family Tree DNA. Today, this report is the single best option
for measuring a person’s overall ethnic ancestry.By comparing your DNA to that of global populations, it does what’s called a biogeographical analysis.
As part of Family Finder, it uses your autosomal DNA, which reflects the contributions of ALL your ancestors going back at least five or six generations.
Some companies market tests that claim to make finer distinctions than this. But their reports are based on such tiny population samples that the results are mostly wishful thinking.
Population Finder is the most scientifically credible ethnic DNA test available today.
