Interpretive Summary:

Technical Abstract: The Eastern oyster (Crassostrea virginica) occurs naturally and abundantly along the Atlantic coast of North America and coasts in the Gulf of Mexico. We have conducted a large-scale sampling effort along this range and performed whole-genome sequencing of selection line and wild populations. In doing so, we have been able to generate valuable data to investigate questions pertaining to epigenetics, evolutionary history and dynamics, and genetic diversity. Here, we present our investigation of the underlying genetic population structure and variation found in the sampled populations. Additionally, we present an analysis of genetic outliers and findings of loci potentially under spatially heterogeneous selection.
