Karyogram

 A Karyogram is a way used to depict chromosomes, the way chromosomes are organisded in the image makes them easy to visulise they are arranged in to homologous pairs each of which is arranged in to size order- from largest to smallest.  The most common form of Karyogram shows photographs of chromsomes, the photographs are taken during meiosis at which point chromosomes are condensed and become visable where they would other wise not be visable as descrete entities. In the image the chromsomes appear to have a banding pattern this is produced as a result of staining, the chromsomes are stained so they can be seen and interperated in the image where otherwise this would not be possible.
