[Do external or internal reasons determine the synchronicity of cell division at early stages of embryogenesis?]

By the method of computer simulation the 2-dimensional diagram, which reveals the dependence of the degree of cell division synchronization on genetic variation and environment variety, was obtained. The diagram demonstrates many trajectories of the cell system self-organization. It was shown that synchronization on the early stages of loach spawn embryogenesis may be obtained by the combination of various internal and external factors.
