title: [Frequency of acrocentric chromosome associations in human blood lymphocytes when using different methods for its assessment].
abstract: The indeces of frequency of associations of acrocentric chromosomes in lymphocytes of human peripheral blood were compared with the help of different criteria of their estimation: by argentofile connections and by specific location of acrocentrics in metaphase plate. It was shown by the methods of variation statistics that the specificity of orientation of associative acrocentric chromosomes towards each other by short arms to the distance equal to the length of G-chromosome long arm is not accidental. Therefore, the method elaborated on the basis of the estimation criteria reflects participation of acrocentric chromosomes association in the formation of general nucleus in interphase more completely than the Ag-method, as preservation of Ag-material depends on the extent of its resorbtion in mitosis.
