 A Karyogram is a way used to depict chromosomes, the way chromosomes are organisded in the image makes them easy to visualize. They are arranged in to homologous pairs each of which is arranged in to size order- from largest to smallest[1].  The most common form of Karyogram shows photographs of chromosomes, the photographs are taken during meiosis at which point chromosomes are condensed and become visible where they would other wise not be seen as discrete entities[2]. In the image the chromosomes appear to have a banding pattern this is produced as a result of staining, the chromosomes are stained so they can be seen and interoperated where otherwise this would not be possible[3]
