Groups as trees.

A) Photograph of a cross-section of the yeast snowflake phenotype shows the branching morphology. B) Simulated group growth from a single cell (Node 0) after 6 rounds of cell reproduction (generations). The different colors represent different branches emanating from Node 0. The numbers inside nodes represent the generation of their birth.
