Figure 2: Modelling the snowflake yeast body plan.
From: Origins of multicellular evolvability in snowflake yeast

(a) Cluster growth from a single cell, with each distance from the basal cell (purple) labelled a different colour. (b) Pascal’s triangle describes the number of cells distance x from the basal cell. (c) The model accurately predicts the growth form of snowflake yeast. Despite a 45% increase in settling speed over 227 days of evolution21, we find no differences in the growth form of any of our snowflake yeast isolates. Inset: a cluster with each cell’s position from the basal labeled.
