(((( Rob )))) My old friend, I know... all too well...
What you said back at the beginning of this thread (which I'm just now reading for the first time) about spending some time with your parents? I highly recommend it. Trust me, no matter how much bad water has passed under the bridge, if you don't try, you'll regret it someday.
Regrets. Another thing about bein' in your 40's...

Hello all. Guess I've been around awhile - never posted alot, but I used to spend a whole lot of time here. Nowadays I just look in every once in awhile. It's always good to see that everyone from the old days hasn't completely disappeared ( I miss you too, April ).

((((((Tatiana)))))) Sending my thoughts your way.
Kellee is sure a cutie.
I know those old scars never heal, but blessings like your new Kellee make 'em a little easier to live with.
Take care, old friend

Like I said earlier, BSE ("mad cow disease") and it's human form CJD, come from ingesting animal proteins already infected with BSE. It is not heritable or genetically transmitted. These specific proteins, called prions, are found only in the brain and upper regions of the spinal chord of affected animals, not in the muscle tissue that is normally consumed, nor even in the other organs sometime consumed (not that I'd advocate eating any part of an affected animal). Incidently, it's never been found in a bovine less than 30 months old.
Alot of people still seem to have this sci fi image of cloning, where the mad scientist straps someone down on a table and points some mysterious ray at them and the other end of the machine spits out an army of clones of identical age, size, and appearance who act and think exactly like the original... It's actually a matter of isolating an individuals dna, placing it in an embryo that has been emptied of it's own dna, placing that embryo in a surrogate mother, and allowing it to proceed on it's own. The resulting animals will have the same dna (like identical twins), and will obviously be very similiar in appearance to the original and one another, but will likely vary somewhat in appearance due to differences in enviroment, nutrition, etc... It's science, not magic...

I see what you mean that some ill effects from erosion and/or concentration of the original dna seems possible if one were to continually make clones from clones. I know of a number of animals to which several clones exist, but all of them were produced from the original cell line, not from one another, so I've never really considered it in those terms. An established cell line can be produced from, probably not infinitely, but the number of times appears to be far more than has been reached, as far as I know. So aside from pure research, there's really no reason to clone a clone - a large percentage of the cost of cloning is in establishing the original cell line, so from a commercial aspect, multi generation clones make little sense.
Right now, the vast majority of clones in the beef cattle industry are of bulls that sell alot of semen for AI, and the rest are of elite females that sell embryos and/or progeny at high prices and in large numbers. It's not really replacing sexual reproduction, just making more of the same generation so they can make more of the next. Alot of these bulls can easily sell 100,000 units of semen a year at $50 per unit (for example), if they can produce it - thus the value of clones. These cattle won't remain this popular forever, though a very select few may continue to be used (in continually lesser amounts) for several years. Each generation will produce it's new "stars", and the breeders will keep moving on.
My biggest objection is simply that it reduces genetic diversity. Between that and the fact that it will prob'ly always remain relatively expensive and complicated, I really don't think it's going to ever get a whole lot more concentrated (in the beef industry) than it already is.
Hopefully, it's true value will be in medical and genetic discoveries, not in selling bull semen anyway.

Exactly, drwtsn32.
james_woods, BSE, or "mad cow disease", is not genetic, nor is it heritable. It is contracted by the animal eating other animal based proteins (usually blood and/or bone meal), so nothing about cloning increases the BSE risk whatsoever.

It's not likely that we have or will be eating meat, at least in any noticeable amount, from clones themselves anytime soon. Producing a clone is still far too expensive to be viable for actual meat production. The meat animals that are being cloned commercially are proven breeding stock whose progeny (including semen or embryos) have proven valuable enough to make the cloning process worthwhile. Many of their offspring have made it to the plate, though.
A clone is both genotypically and phenotypically simply an identical twin to the animal it originated from. There's no difference in the meat or anything else of an animal conceived by cloning and one conceived naturally. I've been around several bulls that are clones, and have used a few of them via artificial insemenation. Without exception, they breed just like the original they were cloned from.
I think cloning is now where artificial insemenation, embryo transfer, invitro fertilization, etc... were in their early stages - people just don't really understand it. Back in the early 70's my mother went as far as recruiting the local elders to tell my dad and older brother that they shouldn't be a.l.'ing cows because it wasn't natural. A few months later my brother made a trip to Bethel and the Watchtower farm with several other JW's, including a couple of said elders. They found not a single bull at the farm - all of the cows there were being bred a.i...

Okay.
