Abstract
It has been demonstrated that the observed ratio of phenotypes of marker enzymes in some sugarbeet plants produced by mitotic agamospermy can only be explained by different degrees of endoreduplication of chromosomes carrying different alleles of the enzyme loci. In these plants, different patterns of variability of the enzymes controlled by the linked loci suggest different degrees of endoreduplication of different chromosomal regions. A concept of multidimensional encoding of inherited information in eukaryotes has been proposed.
