[A method of forming analogous groups for selection-genetic research]

A method of forming groups of animals similar in a complex of characteristics is proposed. All the objects are represented by a linear diversity of an n-dimensional space Yi=xij containing the basis Yr. The criterion of the appurtenance of the object to a definite group is the value Yi--Yr min. The intra-group variation can be reduced provided the requirement Yi--Yr less than or equal to R. The method proposed affords the possibility of an abjective formation of groups of animals similar with respect to a complex of biological characteristics with the extent of heterogeneity required for the investigator. The method proposed is easily formalized and can be realized by means of computer.
