Abstract

Genome-wide Association Studies (GWAS) have played a crucial role in uncovering the genetics underlying complex human traits. Recently, there has been considerable interest in adapting GWAS-like methodologies to investigate pathogenic bacteria. Despite the variety of methods proposed, there remains a lack of clarity on how to effectively model the intricate population structures found in bacterial…
