THE SPATIAL REORGANIZATION OF CHROMOSOME ARCHITECTURE GENERATIVE SYSTEM IS A MECHANISM OF SALTATIONAL SPECIATION
Journal Title: Фактори експериментальної еволюції організмів - Year 2016, Vol 18, Issue
Abstract
Speciation can not be regarded as a long-term process of gradual adjustment ancestral species gene pool. The concept of «gene pool» entirely relates to the polymorphic part of the genome, while it is clear that speciation events affect primarily monomorphic (invariant) and part of this is accompanied by irreversible reorganization of its regulatory system. Saltational speciation, based on the emergence of spatial reorganization of the architecture of the chromosomes in the generative system most likely to occur in a critical influence of abiotic and biotic factors, which are defined as environmental conditions periphery.
