Yer, Dolly was cloned from a 6 year old sheep, ergo when the clone was born she was already 6 years old?
Common sense tells me that anything using tinkering with dna is most likely speculation. Let me explain. Scientists say 'oh, this is junk dna, we don't need to worry about it.' they only say this because thay haven't figured out what it actually does yet. Until you understand something completely, how can you say whether or not any part of it is redundant/useless or whatever? When we figure out how dna works in its entirety for the 'thing' we are modifying (like foodstufs, be they animal or plants) then perhaps I'll be convinced that it's safe to eat, without causing my children to be born with two heads! You only hvae to look at the result of well meaning scientists and their meddling with animal feed - 'I know! Lest grind up dead animals mix it with some other plant based stuff and turn them into cattle feed pellets!' Kill 2 birds with 1 stone: make money and more animal feed. What they didn't know was the result of feeding crushed spinal matter and the like back to animals which are evolved to eat plants - contamination of the food chain leading to transmittal of BSE in cattle to humans. Score one for science.... not.

Well, concidering that we know how aging works we can indeed say that dolly was 6 years old at birth, at least in some respect. Anyway what governs aging is tolomere, a sequense in the dna that becomes shorter every time the dna molecule is copied, limiting the ammount of times it can do so. Because the sheep Dolly was cloned from was 6 year sold and therefore had allready lost 6 years owrth of telomere from its dna chain dolly had a shorter life than a completely naturaally born sheep would have.

That may be what killed her, but if you the genetic abnormalities continue, and nature continues with its habit of mutating, especially when the telomeres of a cell are gone resulting in permanent mutation and loss of genetic information, so I will not ever trust it.

I am so glad I don't eat meat. :p
They better bloody lay of doing the same thing to fish, I love fish. Watch out Skybird here I come, 9000 posts. ![]()

So, regardless of your feelings on clones, you would still be buying meat made "the old fashioned way". The breeder would replace his clones from frozen embryo's taken from the original 1%. In order to avoid inbreeding depression, he would periodically outbreed some animals with a different male, and then again reselect the best breeders from that to replenish his clone stock. The cost saving is foreseen to be in the ability to select only the very best breeders, and then focus exclusively on them via cloning. It removes a lot of the money lost due to the variable breeding success in a variable herd. Actually, as a business model, it still remains to be proven effective. And there will be a need for breeders to be careful not to deplete whole breeds or strains of animals of too much genetic variation (although most commercial farm animals are already highly inbred, deliberately so, by selective breeding). But they also keep things genetically mixed up somewhat by normal sexual reproduction (and its inherent recombination) of the market stock, and periodically re-selecting the breeders for cloning from that.

I am realistic and know that the selling of gen-food and now clone-food will spread. I am against it, but i cannot help it. No consumer ever told the companies to invest in that, but they did, unwanted, and now want to enforce it onto us for their precious profits.
However, what I really hate and get hot about is: what lying efforts are taken by the EU as well as national law makers and politicians to prevent that clear marking of such food is obligatory to be practiced. In germany, yes, gen-food needs to be marked as that - but only in the smallest of smallprint, and only when certain treshhold levels are surpassed, and only when the genetic manipulation in the vegetable for example did not exceed a certain limit. Even more, such changed products even can be misleadingly labelled as "bio" food! we have a "consumer protection ministry" in germany. It really does honour to it's name: it successfully protects the industry against consumers. they want to shove the sh!t down your throat against your will, and without you being able tell. "If you meet politician, kill politician" - nine out of ten are telling lies the moment they open their mouths, and they will appeal to the lowest of man's instincts, and they will sell you easily and all too willingly if they have a profit from it. No gen food and no clone food over here, thanks. At least as far as I can tell by the intentionally misleading labels.

Unfortunately, clones do have shorter lifespans than normal creatures. They're definitely not the same as naturals, but what causes them to die we can't be sure of. For instance, to perfect Dolly, over 200 attempts were made. And that's not all:
Seventy calves have been created from 9,000 attempts and one third of them died young; Prometea took 328 attempts. Notably, although the first clones were frogs, no adult cloned frog has yet been produced from a somatic adult nucleus donor cell. I'm skeptical about cloning food... there's definitely a downside to it somewhere along the line... |
