The sporadic occurrence of 2n=36 in a few cells of Citrus reticulata is another indication for x=9 as the true basic number of the genus Citrus. The basic chromosome number of Citrus (Rutaceae) and other related genera of the subfamily Aurantioideae has been reported as x=9 (Frost 1925).

Which animal has the highest number of chromosomes?
The mitotic and meiotic chromosomes of the semiaquatic rodent Ichthyomys pittieri (Rodentia, Cricetinae) from Venezuela were analyzed by means of conventional staining and several banding techniques. The diploid chromosome number of this rare species is 2n = 92, which is the highest value known for mammals.
