Analysis of DNA of male and femaleSphaerocarpos donnellii Aust. (Liverwort)

The karyotypes of females and males ofSphaerocarpos donnellii differ in that there is a large essentially heterochromatic X chromosome in the female (approx. 25 volume-% of the autosomes) and a small Y chromosome in the male (0.1–3 volume-% of the autosomes). DNA from females and males differ in buoyant densities in cesium chloride equilibrium gradients (1… (More)
