Here, B represents B chromosome and its variation in the number between individuals.[82][83] [82] Capuchin monkey (Cebus x) 54 [84] Silkworm (Bombyx mori) 56 This is for the species mulberry silkworm, B. mori (2n=56). Probably more than 99% of the world's commercial silk today come from this species.[85] Other silk producing moths, called non-mulberry silkworms, have various chromosome numbers. (e.g. Samia cynthia with 2n=25–28,[86] Antheraea pernyi with 2n=98.[87]) [88] Strawberry (Fragaria) 56 This number is octoploid, main cultivated species Fragaria × ananassa (2n = 8x = 56). In genus Fragaria, basic chromosome number is seven (x = 7) and multiple levels of ploidy, ranging from diploid (2n = 2x = 14) to decaploid (F. iturupensis, 2n = 10x = 70), are known.[89] [89] Gaur (Bos gaurus) 56 Elephant (Elephantidae) 56 Woolly mammoth (Mammuthus primigenius) 58 extinct; tissue from a frozen carcass Yak (Bos mutus) 60 Goat (Capra aegagrus hircus) 60 Cow/Bull (Bos primigenius) 60 American bison (Bison bison) 60 Bengal fox (Vulpes bengalensis) 60 Gypsy moth (Lymantria dispar dispar) 62 Donkey (Equus africanus asinus) 62 Scarlet macaw (Ara macao) 62–64 [90] Mule 63 semi-infertile (odd number of chromosomes – between donkey (62) and horse (64) makes meiosis much more difficult) Guinea pig (Cavia porcellus) 64 Spotted skunk (Spilogale x) 64 Horse (Equus ferus caballus) 64 Fennec fox (Vulpes zerda) 64 [55] Echidna 63/64 63 (X1Y1X2Y2X3Y3X4Y4X5, male) and 64 (X1X1X2X2X3X3X4X4X5X5, female)[91] Chinchilla (Chinchilla lanigera) 64 [57] Nine-banded armadillo (Dasypus novemcinctus) 64 [92] Gray fox (Urocyon cinereoargenteus) 66 [55] Red deer (Cervus elaphus) 68 Elk (Wapiti) (Cervus canadensis) 68 Roadside hawk (Rupornis magnirostris) 68 [93] White-tailed deer (Odocoileus virginianus) 70 Black nightshade (Solanum nigrum) 72 [94] Bat-eared fox (Otocyon megalotis) 72 [55] Sun bear (Helarctos malayanus) 74 Sloth bear (Melursus ursinus) 74 Polar bear (Ursus maritimus) 74 Brown bear (Ursus arctos) 74 Asiatic black bear (Ursus thibetanus) 74 American black bear (Ursus americanus) 74 Maned wolf (Chrysocyon brachyurus) 76 Gray wolf (Canis lupus) 78 Golden jackal (Canis aureus) 78 [55] Dove (Columbidae) 78 Based on African collared dove [95] Dog (Canis lupus familiaris) 78 Normal dog karyotype is composed of 38 pairs of acrocentric autosomes and two metacentric sex chromosomes.[96][97] [98] Dingo (Canis lupus dingo) 78 [55] Dhole (Cuon alpinus) 78 Coyote (Canis latrans) 78 [55] Chicken (Gallus gallus domesticus) 78 African wild dog (Lycaon pictus) 78 [55] Tropical pitcher plant (Nepenthes rafflesiana) 78 [34] Turkey (Meleagris) 80 [99] Sugarcane (Saccharum officinarum) 80 This is for S. officinarum (octoploid, 2n = 8× = 80).[100] About 70% of the world’s sugar comes from this species.[101] Other species in the genus Saccharum, collectively known as sugarcane, have chromosome numbers in the range 2n=40–128.[102] [100] Pigeon (Columbidae) 80 [103] Great white shark (Carcharodon carcharias) 82 [104] Hedgehog genus Erinaceus (woodland hedgehogs) 88 Moonworts (Botrychium) 90 Hedgehog Genus Atelerix (African hedgehogs) 90 Grape fern (Sceptridium) 90 Pittier's crab-eating rat (Ichthyomys pittieri) 92 Previously thought to be the highest number in mammals, tied with Anotomys leander.
