Examples of distribution of C-heterochromatin in mammalian chromosomes. a. C-banded chromosomes of the Eurasian shrew (Sorex araneus, 2n = 21). Example of the smallest amount of heterochromatic bands in mammalian genome. b. C-banded chromosomes of the Ground squirrel (Spermophilus erythrogenys, 2n = 36) with very large centomeric C-bands. c. C-banded chromosomes of the marbled polecat (Vormela peregusna, 2n = 38) with the largest additional heterochromatic arms on some autosomes. d. C-banded chromosomes of the Amur hedgehog (Erinaceus amurensis, 2n = 48) with the very large telomeric C-bands on autosomes. e. C-banded chromosomes of the Eversmann's hamster (Allocricetulus eversmanni, 2n = 26) with pericentomeric C-bands on the X and Y chromosomes. f. C-banded chromosomes of the Southern vole (Microtus rossiaemeridionalis, 2n = 54) with very large C-bands on both sex chromosomes.
