Table 2. Didemnum vexillum experimental Set I ramet size increases.

Ramets A–D were paired in six pairwise combinations in duplicate and percentage area/day for each ramet was determined. nd - not done. Values for the last days of observations were calculated from the cumulative relative distributions of genotypes (as determined by microsatellite genotyping) in all tissue samples for each chimera. Refer to Fig. S1 for the detailed information on the relative distributions of genotypes in each tissue sample.
