Interaction of two bodies. a. Colonies (at 7d, tens per dish) sown as single clones (F, R), or as mixtures of two clones (F + Fw, etc.). Note confluence in rimmed clones, as well as the X structures appearing in mixtures of rimmed-rimless clones (arrows). b. Planting (dotting) of a colony to the vicinity of a pre-existing colony (1, 2, or 3 days old, as indicated to the left); seen 3 days after dotting. Note strong pattern distortion in younger partner in all combinations; confluence of rimmed partners, in contrast to rimless ones; and encircling the rimmed partner by the rimless one. c. Plantings of mixed suspensions (cell ratio as indicated, bar = 1 cm). Two rimmed clones (FFw) give rise to highly variable structures resembling F-bodies, (three parallels from a single experiments shown). A mixture of rimless clones (RW) tends to maintain the identity of each clone. in combinations rimmed-rimless the rimmed partner becomes overgrown, albeit both cell types persist in the center.
