Chromosome painting of normal karyotype (type I) and translocation heterozygotes (type IV) in Quasipaa boulengeri. Scale bar = 5 μm. a type I, fluorescent signals were detected only in the largest pair of homomorphic chromosome 1 (white arrows). b type IV, fluorescent signals were observed in the largest metacentric chromosome 1, the telocentric chromosome including part of chromosome 1, and a large sub-telocentric chromosome 6 (white arrows)
