title: [Interpretation of various ratios of genetic parameters in Hayman's diallelic analysis].
abstract: The genetical algebra of diallele analysis was used to interpret some relations of genetic parameters which were not earlier applied in research of genetic control (GC). It was discovered that in the case of gene correlation, the relation H2 greater than H1 is possible, meaning the regression among frequencies of alleles in loci. We demonstrated, in what way to distinguish two reasons for changes in H1, H2 and h2, when an external treatment is applied: Due to frequency changes of dominant and recessive alleles in the majority of loci, in case new loci are involved in GC; Due to changes in dominance contributions. The latter could provide new information about a situation in loci by analysing the changes in h2 and the correlation coefficient of parental trait levels with their dominant properties as well as changes in D. A few experimental examples illustrate the theory implication.
