The cultivated carrot (daucus caroto L.) has a chromosome number of 2n = 18.
The carrot is a diploid species and has nine relatively short, uniform-length chromosomes (2n = 18). The genome size is estimated to be 473 mega base pairs.
The cytogenetic characterization of the carrot genome (Daucus carota L., 2n = 18) has been limited so far, partly because of its somatic chromosome morphology and scant of chromosome markers.
