Abstract

Learning Objectives:

• Identify the discriminating information provided by allele frequency differences among reference populations for ancestry predictions.
• Evaluate evidence to make predictions of potential source populations of an individual.
• Develop the concept that an estimate of ancestry composition including admixture is produced from fine-grained fitting of many SNP markers across multiple populations.

This classroom exercise demonstrates the logic behind the modeling applied to estimate ancestry composition from an individuals’ SNP data.
