Roman numerals (I∼V) represent five karyomorph types.
The bold mumbers and letters indicate the homologues of no. 1 and no. 6 and their cenromere position, respectively.
M =  large metacentric chromosome; m =  small metacentric chromosome; Sm =  large submetacentric chromosome;
sm =  small submetacentric chromosome; St =  large subtelocentric chromosome; T =  large telocentric chromosome.
Variations exist in the types of chromosome no. 1 and no. 6.
