[The prospect of studying genetic systems using an informational-logical approach].

A new information technology, the information-logical approach (ILA), which is based on information theory methods and the fuzzy sets theory, is considered. This method can be applied for the majority of biological and ecological studies, and in genetics. In breeding and genetic studies, ILA can be used as a basis for the development of methods that will allow one to take into account ecological, geographic, climatic, and other peculiarities of trait expression that influence productivity. Application of ILA also opens new prospects for analyzing results of genetic and ecological monitoring (e.g., post-Chernobyl' monitoring) to predict further behavior of the systems studied. This paper presents a general outline of information analysis, describes a block of one-factor analysis, which was implemented on a personal computer and has a user-friendly interface, and also presents several examples concerning application of ILA to specific genetic systems.
