A friend of mine is offering a free genetic modeling service through the site Bread DNA, using qpAdm, a well-established tool employed in serious genetic studies.
qpAdm estimates ancestral origins by comparing your DNA to ancient populations, following rigorous scientific methods.
The reliability of the model is assessed through a p-value:
If the p-value is above 0.05, the model is considered acceptable.
For example, my own result has a p-value of 0.58, meaning it is considered reliable.
(i'm strictly 75% ethnic French and 25% sardinian) :
74.9% France Occitanie (Bronze Age)
25.1% Sardinia (Iron Age)

This is a serious service based on scientifically recognized methods.

Understanding the p-value in qpAdm:
In a qpAdm model, the p-value helps check whether the proposed model (the explanation of your ancestral origins) matches your genetic data.
A p-value above 0.05 means the model is statistically acceptable: your DNA fits well with the selected ancient populations.
A very low p-value (e.g., 0.01 or lower) suggests the model is a poor fit.
In short:
p-value > 0.05 = credible model
p-value < 0.05 = questionable model
The p-value doesn't represent a "success percentage"; it simply tests whether your ancestry model could realistically explain your genetic data without being statistically rejected.
However, you don't have to worry too much about the p-value.
If this concept feels too technical, just know that the individual offering the service does not select models that fail.
As stated on the site, models with a p-value below 0.05 are discarded and not reported.
