Examples of basic karyotype measurements and idiogram constuction by DRAWID. A Chromosomes of C. sativa (2n = 20); sex (black color) and NOR-bearing (green color) chromosomes are highlighted B Idiogram of Rosa wichurana; satellites on chromosomes 13 and 14 are colored in red C Idiogram of Allium fistulosum after measurement of the chromosomes, and application of the function “reduce karyo” merging homologuous chromosomes to obtain a monoploid idiogram, standard deviation bars are shown D Idiogram of Allium cepa constructed after measurements of 3 metaphases and application of the “get average karyo” function to obtain the average idiogram, standard deviation bars are shown.
