STRUCTURE analysis of genetic treatment levels.

Bar plot resulting from STRUCTURE analysis based on an eastern oyster-specific SNP multiplex panel for a subset of oysters (24 oysters per genetic group) used in the mesocosm experiment. Offspring from the five parental pairs are labeled A–E and polycultures are random mixes of the monocultures. Each vertical line (bar) represents an individual oyster. For example, a solid blue vertical bar is an oyster with a genetic make-up from the “B” group, whereas an oyster with a vertical bar of two different colors indicates a genetic make-up from the two groups corresponding to the two colors.
