G25 vs qpAdm
I’ve been trying to understand the practical differences between G25 and qpAdm, especially for West Asian / Middle Eastern ancestry modeling where populations are highly overlapping genetically.
For those with experience in ancient DNA modeling:
In your experience, is qpAdm genuinely more reliable than G25 for ancestry modeling when the model is built carefully (good sources + proper outgroups)?
What is the general opinion among advanced hobbyists or people familiar with population genetics regarding the qpAdm/AdmixLab system on Illustrative DNA?
I know it’s not the same as fully manual academic qpAdm workflows, but would you still consider it significantly better than standard G25 calculators if the references and outgroups are chosen correctly?
I’m especially interested in opinions from people who have actually worked with qpAdm, ADMIXTOOLS, or complex Middle Eastern models.
