Delphinieae Chromosome Database
DCDB offers three types of chart searches. Filters can be combined to restrict the records represented in each graph:
▪ By countries (or regions): percentage of chromosome counts by country (or region)
Displays the geographical distribution of matching chromosome records. The pie sectors represent the percentage of records reported for each country or region.
▪ By chromosome counts (2n): distribution of sporophytic chromosome numbers
Displays the frequency distribution of sporophytic chromosome numbers (2n) among the records that match the selected taxonomic and geographic filters.
▪ By chromosome counts (n): distribution of gametophytic chromosome numbers
Displays the frequency distribution of gametophytic chromosome numbers (n) among the records that match the selected taxonomic and geographic filters.
