Coffea arabica Bourbon Genome

Coffea arabica is a polyploid species, carrying four copies of the eleven chromosomes typical of the genus Coffea, totaling 44 (2n = 4x = 44). Technically, it is described as an allotetraploid genome, the result of a hybridization between two diploid species, Coffea canephora and Coffea eugenioides, which doubled arabica's chromosome number to 44.
