[Experimental verification of several assumptions and methods of statistical genetics. II].

The applicability of A. S. Serebrovsky's formulas and N. A. Sobolev's methods was investigated for a dihybrid cross. It was shown that Serebrovsky's formulas do not always lead to a correct estimation of the minimal number of genes by which the parents are distinguished. In the case of gene interaction this estimation sometimes proved to be exaggerated 2-4 times. A test of Sobolev's method demonstrated that this method cannot be considered as reliable for work. Most of his estimations are not correct. Various estimations of the same phenomenon are often contradictory.
