Polymorphism in the location of the 18S and 28S rRNA genes on the chromosomes of the diploid-tetraploid treefrogs Hyla chrysoscelis and H. versicolor

The chromosomes of the diploid Hyla chrysoscelis and its tetraploid sibling species H. versicolor were studied with AgNO sub(3) staining and in situ hybridization to determine the chromosome location of the 18S and 28S ribosomal RNA (rRNA) genes. A total of 236 Hyla chrysoscelis) from 34 localities...

Description
Summary:The chromosomes of the diploid Hyla chrysoscelis and its tetraploid sibling species H. versicolor were studied with AgNO sub(3) staining and in situ hybridization to determine the chromosome location of the 18S and 28S ribosomal RNA (rRNA) genes. A total of 236 Hyla chrysoscelis) from 34 localities in 15 U.S. states and 100 H. versicolor from 15 localities in 12 states were examined. Possible explanations include inversions, translocations, mobile genetic elements or a combination of some or all of these.
