How Robust Are Genomic Offset Predictions to Methodological Choices? Insights From Perennial Ryegrass.

Molecular ecology - 1 Jul 2026

Abstract excerpt

Genomic offsets are increasingly used to quantify the mismatch between a population's current genetic composition and the composition predicted under changed environmental conditions. While genomic offset is a promising tool for assessing climate maladaptation, the sensitivity of predictions to different methodological choices is not well understood. In this study, we compared two fundamentally different...
