Chloroplasts

Ben,

You skirted my question.  Why would one part of the Hosta genome have higher
mutation frequencies than another.  For this proposition to be true, there
would have to be a mechanism for it.  What is the mechanism.  I fear that
most of what we are discussing are hypotheses without data.  They may be
good hypotheses, but are the proven?  Are there other examples of volatile
genes' in other plants where there is data.  We come back to the original
reason for the discussion of transposable elements, they are a mechanism for
an unstable portion of the genome.

Here a possible mechanism explaining differences but there are many. Mutations arise in the DNA. All organisms have extensive mechanism (repair enzymes ) to deal with that Occasionally a mistake escapes .....
