<p>What is the minimum number of individuals required per group (population/species) for an <a href="https://genome.cshlp.org/content/19/9/1655.full" rel="noreferrer">ADMIXTURE</a> analysis to be appropriate?</p>

<p>Is there a way to determine this number mathematically based on the amount of genetic data I have or other criteria?</p>

(Asked by: username_0 on 2018-11-01)

What is the minimum number of individuals required per group (population/species) for an [ADMIXTURE](https://genome.cshlp.org/content/19/9/1655.full) analysis to be appropriate?

Is there a way to determine this number mathematically based on the amount of genetic data I have or other criteria?

Are there any citations I can use to figure this information out?
