GD² - GCU
The GD² database (Georeferenced Database of Genetic Diversity) contains genetic and georeferenced passport data of different genetic units (populations, single trees) that are traditionally analyzed in genetic surveys conducted in natural populations.
Genetic data include marker data (Isozymes, Microsatellites, Single Nucleotide Polymorphisms, PCR DNA fragments etc...) coming either from diploid or haploid tissue for which genetic parameters have been calculated (allelic or nucleotide frequencies, diversity statistics). Passport data include all other data than genetic, ranging from geographic coordinates to ecological data of the location of the genetic units. Genetic units are either single individuals or natural populations on which the genetic and passport data are recorded.
The GD² database is available here
From this page it is possible to view the GD² unit mapped with the GCUs for all available species. It is also possible to filter the units by distance.
