Chromosome Number of Rice – Ploidy and Representation

Rice (Oryza sativa) has a small genome of about 0.4 Gb (the size mentioned is that of the haploid genome in each of the cases); it has the simplest of the monocotyledonous genomes. The chromosome number is 2n = 24, n = 12 chromosomes.

The genome of rice comprises 12 chromosomes (2n=24) with a total length of 430 Mb (megabase, a nucleotide length with base pairs – 1000 000) corresponding to about 1500 cM (centiMorgan). In rice, hence, each cM refers to a mean of 290 kb with meiotic recombinations of 15. There is a great variation between different species of rice with these statistics mentioned when it comes to the genome size. Compared to common cereals, rice has a small genome of about 430 Mb.
