Comparing theoretical topological division rules with the experimental data. Division matrices for post-mitotic neighbour number likelihood for the different division rules as well as the experimental data, with the pre-mitotic neighbour number of the cell along the edge and the post-mitotic neighbour number of a daughter cell along the top. The elements indicate the probability that a cell with a given number of neighbours gives rise to a daughter cell with a specific number of neighbours. For visual guidance, green to red colour coding indicates relative likelihood for a given pre-mitotic neighbour number. (A) ‘Equal split’ rule. (B) Arabidopsis PC data. (C) ‘Pascal split’ rule. (D) ‘Random split’ rule.
