[The first exploration of the properties and laws of mutation plastids transmitting with cell division]
Abstract:
Suppose there are m plastids in an initial cell, in which i plastids are mutated. In the this paper we discuss the probability that m mutated plastids are distributed in a cell simultaneously during in the process of mutant plastids dividing and randomly distributing with cell division. Let x(t) = 1 denote the stochastic event that a cell contains only mutant plastids in t-th division and x(t) = 0 denote the opposite event. We may find some properties of the stochastic process ¿x(t), t epsilon T¿ demonstrating that the process is a Markov chain. Finally we can obtain the matrixes of transition probability between homogeneous heterogeneous plastids, this reveals some laws of mutant plastids transmitting with cell division.
