Genetic monomorphism - it's the law of biology, explaining the stability of the organs and functions of a living organism from generation to generation and the dependence of the viability of the organism from this stability.
The law has been identified as a result of years of research in 70-s of XX century a number of Soviet scientists, including academics Y.P. Altukhov, G. Rychkov and L. I. Korochkin.
It was quite obvious that the important function of the form of a living organism (in charge of that man - a man, a monkey - a monkey, a dog - a dog) are encoded by genes that do not admit of variation, otherwise the body just dies without leaving a chance and possible evolutionary changes.
Studies have shown that the monomorphic genes (which account for approximately two-thirds of the entire genome) in different organisms are quite different, and any changes in them fatal. Thus, changes in key monomorphic gene leads either to the inability to develop further, or to the fact that the organism cannot survive in the environment and the harmful effects of natural selection.
Polymorphic genes allow changes and control the symptoms of unimportant species, called adaptive, for example, different color eyes or hair, density of undercoat and dogs, etc.
The discovery of this law shows that the genetic changes are possible only within a species, and any change concerning the vital and defining features of this form of monomorphic genes is lethal, the body can not in principle to move to a different, higher in the hierarchy of living organisms level.
