Figure 1From: Karyotype variation is indicative of subgenomic and ecotypic differentiation in switchgrassGenome reduction in dihaploid individuals. Chromosome squashes prepared from root tip cells confirmed 2n = 36 chromosomes in the tetraploid cultivar Kanlow (a) and 2n = 18 in dihaploid ALB280 (b). Scale bars = 5 μm.Back to article page
