Did you actually read the article properly?One good example of cloned every day food.
Every single banana we eat is a clone, they are all Cavendish variety, and there are already signs that this monoculture will lead to them being destroyed as a crop within 20 years, thanks to the fact that any parasite or disease will have universal efficacy.

That like marrying your cousin repeatedly through the generations leading to less resistance to diseases, that why the Roman law does not allowed it.Did you actually read the article properly?
Yes, 90% of the dessert bananas produced are Cavendish. Dessert bananas constitute 15% of the bananas consumed, therefore 86.3% of bananas are not Cavendish.
By the strict definition of cloning as asexual reporoduction then yes, bananas are clones. There was a genetic mutation that turned the had black seeds into mush, but made it more edible. This meant plants had to be propogated via cuttings, budding, etc - in exactly the same way that many horticultural strains are produced and maintained today. For example, I've quadrupled the number of strawberry plants in my garden this year by propogating the suckers - which is exactly what banana farmers do.
All varieties of banana are suceptible to the fungus mentioned in the article, not just Cavendish. This is why the work into understanding the genome is important. The bit that was not reported is also the work going into understanding the genome of the fungus, so that this can be attacked too.
Most people who propogate plants, etc, would not consider this to be "cloning" in the same sense as animal cloning. Asexual reproduction is not only common in the natural world, but is also genetically stable. Much of the fruit we eat today is produced through propogation, or asexual reproduction.
When it comes to higher-order animals, asexual reproduction is very uncommon. What is done in the lab to clone a sheep, cow, pig or whatever is not an extension of a naturally-occuring process. It produces genetically unstable offspring.
Perhaps there is something instinctive in the way we feel about animal cloning - my grandfather would never counternance animal cloning and would say so while grafting apple trees.
BTW, I'm no banana fetishist - my caribbean in-laws are banana and sugar cane growers and are much better placed to comment than any of us are (good job they are visiting _
I remember Geena Davis' reaction when she ate a steak which Seth Brundle had put through that teleportation machine. She said it tasted funny, and that's good enough for me.BBC News - Cloned cow offspring meat in UK food chain, FSA says
Anyone on here worried?
I don't think I'd lose any sleep with this milk on my Cornflakes or a nice steak on my plate
It is in the animal world, due to genetic instability. Not so in the plant world, where a more stable genome doesn't tend to produce the mutations in quite the same quantity.That like marrying your cousin repeatedly through the generations leading to less resistance to diseases, that why the Roman law does not allowed it.
