Chromosome number |
description |
The plant genome is organized in chromosomes. Chromosome number, basic chromosome number and ploidy level are simple descriptive parameters for species and other taxa. They may change due to evolutionary steps like polyploidisation or aneuploidy. Chromosome parameters are important for taxonomy, evolution ecology and biogeography. Data are given for basic chromosome number, chromosome number of the sporophyte, its ploidy level and ploidy type, whether the number is known from Germany and which is the most common number. |
