Dataset for: Spatial Genetic Features of Eastern Oysters (Crassostrea virginica Gmelin) in the Gulf of Mexico: Northward Movement of a Secondary Contact Zone

These data are bi-allelic genotypes of eastern oysters (Crassostrea virginica) collected along the coastline in each of the major bay areas in Texas. The genotypes were generated via polymerase chain reaction (PCR) of known microsatellite regions in the eastern oyster genome.
