Columns represent the average growth rates of specimen chimeras on either settlement (high-density) or individual (low-density) slides, or after transfer between the two. Growth rates were calculated as number of additional asexually derived zooids in a colony per day, normalized to the original number of zooids. Values of 0 represent clutches in which no specimen grew to a size greater than one zooid. ND indicates that there were no specimens from a given clutch.
