Yh. Zhou et al., Cytogenetic studies of the interspecific hybrids between Hystrix longearistata in Japan and Hystrix duthiei in China, GEN RESOUR, 46(4), 1999, pp. 315-317
Cytogenetic studies of Hystrix duthiei (2n=28) from China, Hystrix longeari
stata (2n=28) from Japan and their artificial hybrids were carried out. The
F-1 hybrids showed a very high degree of bivalent pairing at the meiotic M
etaphase-I. No multivalents were found. Partial fertility of the hybrids wa
s observed. The results indicated that they shared two highly homologous ge
nomes and were closely related.
