Chromosome location of U1 snDNA clusters in eight Gomphocerinae (Acrididae) grasshoppers, shown in metaphase I (a, b, g and h) and diplotene (c, d and f) cells. (e and e') Selected chromosome no. 1 from metaphase I of C. nevadensis showing DAPI pattern (e) and U1 snDNA location (e'). The chromosomes carrying U1 snDNA signals and the X and B chromosomes are indicated. c centromere location. Note the presence of multiple sites on the long (1 and 2) chromosomes of the 2n=17 species (a–e) and the presence of a 2n=23 species with a single U1 snDNA cluster (g) or four clusters on three chromosomes (h). Bar=5 μm.
