Chromosome elimination was studied in squash preparations of seeds of two different Hordeum crosses between diploid parents whose karyotypes allowed identification with unusual ease for Hordeum of the parental origins of the chromosomes being eliminated in each mitosis in embryos and endosperms. In both crosses, the mean chromosome number in hybrid tissues fell during several mitoses until nuclei became haploid in embryos and diploid in endosperms. Elimination was always uniparental, i.e. all… CONTINUE READING
