    When studying asymmetry of bilateral traits, it is very important to take into account their correlation structure. The assumption for quadrivariate normal distribution of traits considers possible models of equality of four correlation coefficients between traits using different criteria and approaches on the basis of two large lamina samples (N₁=500, N₂=521) of drooping birch (Betula pendula Roth.). This study has shown that different traits give evidence of different models of correlation structure.
