Hard inbreeding under extreme environmental conditions is the most important factor of microevolution and speciation

详细

The ideas on the evolutionary value of hard inbreeding under conditions of extreme environmental conditions (especially temperatures) for the processes of the formation of adaptive genetic polymorphism and speciation are substantiated. The main manifestations of the paradoxical effect of hard inbreeding include (1) structural and functional reorganization of the genome of generative (reproductive) system and (2) activation of mobile genetic elements. This can lead to the generation of different types of mutations (gene, chromosomal, genomic, and systemic) and heterochromatin modifications.
