Comparative cytochemical measurements in the diploid-tetraploid species pair of hylid frogs Hyla chrysoscelis and H. versicolor.
Hyla versicolor (2n = 48) is a tetraploid counterpart to H. chrysoscelis (2n = 24). Cytochemical measurements revealed that no cytological parameter of the two species conformed to the expected 2:1 ratio. Every cytological factor of the tetraploid appeared to have been regulated toward the diploid level. H. veriscolor-to-H. chrysoscelis mean ratios and their standard errors were: DNA 1.90 +/- 0.03; nuclear histone, 1.70 +/- 0.18; nuclear RNA, 1.63 +/- 0.19; total nuclear protein, 1.46 +/- 0.05; nuclear sizes, 1.42 +/- 0.08.
