We only place you on a branch your markers actually support. The free preview runs an eligibility check first — if your file doesn’t have enough usable Y-SNPs for a dependable call, we tell you and you’re not charged. For files that pass, we show two depths side by side: the branch we can stand behind, and a provisional branch one step deeper that your markers hint at but can’t yet confirm.
You always see both the depth we vouch for and the depth we’re suggesting — so there’s no “my other test says something different” surprise.
