If my observations are true this is a good example as to why cloning is a negative in the long run. we are alwas talking about biodiversity
So I asked this question how is Tc synonymous with biodiversity?.
I think it's important that if one is going to go mucking around the genome that we fully understand the nature of these genetic variations. If 60% of the world depends on bananas for their starch this is an important food crop. This may appear not to relate to our little hobby but in fact it does these tissue culture labs are making plants of an inferior genetic quality. Without regard to the consequences to the world's Food Supply. I know this may sound alarmist but really consider the consequences

It is true that if you keep using the same line you will get an increased rate of "off-type" mutants. However, this is most commonly seen among the retail end of the science that sell to nurseries in bulk. The people who do research or produce the plants for farmers (such as the lab I work for), know this can be a problem and take the needed actions. In our lab, we only subculture a line 5 times. If we run out material, we go collect a fresh field grown sucker before re-culturing any of our old stock that is at its limit. This greatly reduces the occurrence of off-types and keeps our lines uniform.
