Dynamics of kinetochore–microtubule interaction. a Contour plot of mean first passage time to class 5 starting from class 1 in meiosis I. b–g Probabilities of each class over time for meiosis I (b–d) and mitosis (e–g). n=10 for all panels. γ=1 for meiosis I and γ=0.1 for mitosis. Other parameters are as indicated for each panel. b, e An ideal condition. The probability of class 5 approaches 1. c, f A random condition with no bias towards class 5. The probability of class 4 (merotelic) becomes predominant in meiosis I (c) while class 2 (monotelic) is as prevalent as class 5 (amphitelic) in mitosis (f). Note that classes 3 and 5 have identical probabilities by symmetry in (c). d, g A condition in which the q/p ratio is low. Class 4 persists both in meiosis I and in mitosis
