Hi Peter,
Some slight nomenclatural confusion I think. The nuclear ribosomal DNA is
the DNA encoding the ribosomal RNA, not DNA within a ribosome. "Nuclear"
means that the DNA is part of the chromosomes in the cell nucleus. Because
it is part of the chromosomal DNA, inherited from egg cell and pollen cell,
the ribosomal ITS sequence should identify cases of hybridization that would
not be obvious when using non-nuclear DNA (e.g. chloroplast or
mitochondrial) that is only inherited from one parent.
Regards,
Nick
