So that, the former group effectively play a role as a parameter for controlling to the latter.
Namely, then, as the progress of the latter is regulated by the former, the former is used as an information to determine the initial condition (→ synchronization or hemi-synchronization & control of chaos).
Besides, we must consider about the limits to way to think with dynamical systems on such continuous quantities.
Actually, numbers of respective chemical molecules included in each cell are not so much.
Each number is about below 1000 , it's far from Avogadro's number.
※ On the other hand, researches taking fluctuation into account also were carried out, it has been demonstrated that the process of differentiation is 'robust' to fluctuations in some range.
