Re: HYB:CULT

Is the meta genes like the epigenome for humans?  Where feast or  famine for 
a grandfather can affect the longevity of grandchildren?  I  always wondered 
if the grandkids of drug users will suffer ill affects.

Betty;

A year ago I would have said that seed from stressed  plants would not affect 
the genes of the seedlings. For many years the concept  of acquired 
characteristics was pooh poohed in genetics. If the parents had  good genes then they 
should pass this on regardless of conditions.  

Recently there has been discovered what are called meta genes. What  these do 
is to attach to the normal genes and modify their effect. These meta  genes 
are produced by the parents when undergoing certain environmental  stimuli and 
cane4 be passed on and endow there offspring with some potential  to cope with 
the same type of stress. Therefore if this situation applies in  this case 
(which we have yet to know) then the viable seeds may well be better  adapted 
then even the parents. Maybe Lysenko the Russian geneticist who  destroyed 
Russian agriculture wasn't totally wrong.

Philosophically  this may lead to a few speculations. Perhaps a cross made in 
a harsher  environment may produce better adapted progeny then the same cross 
made in an  idyllic environment.----Bob Pries ( just getting settled in NC,

Several times in the past, we've discussed the health of the  pod parent 
as it relates to the seedlings.

Many of us have had  several months of conditions not favorable to 
irises.  Freeze,  drought, freeze, freeze, heat.

These plants have been stressed big  time.

Can we expect decent seedlings from the pods we have   (assuming the 
parents are good,) or will their poor conditions doom these  babies to 
poor genes?

Will the good genes kick in even if the  conditions were poor?
