• The cytogenetic features of 177 wild-caught Japanese Sika deer, Cervus nippon, were studied in four subspecies collected from Hokkaido (C. n. yesoensis, 27 specimens), Honshu (C. n. centralis, 126), Kyushu (C. n. nippon, 5) and Tsushima Island (C. n. pulchellus, 19). The normal karyotype of Japanese Sika deer consisted of 68 chromosomes (2n=68; 1 pair of medium sized metacentrics, 32 pairs of acrocentrics, and a sex chromosome pair of XX or XY). The majority of these samples exhibited normal karyotypes. However, two types of Robertsonian translocations (LM-1 and LM-2) were observed in a few animals collected from Honshu (5/126, 4.0%) and Tsushima Island (4/19 21.1%).
