Does to me - and it brings us back to my question about genetic drift
<g> in cultivars and potential for different climatic adaptations to
have happened over long time periods when the same cultivar is grown
(propagated) in different climates. So if one DNA pair changes each
time a new rhizome is formed, in 100 years, do you have the same plant?
Taylor's Encyclopedia of Gardening has quite a bit to say about sports
(which it also equates to mutations) which I will report when I get a
minute. One thing they mention is that some species are much more prone
to visible sports than others.
