clone semen

[openas_shorthorn]

why is clone semen so much cheaper then the original ???

 

[ai er]

There's so much more of it on the market. Usually the original can't keep up with the demand, whether due to age, injury, etc. Some people will only use the original though.

also, the clones are not exact copies genetically, so, they could breed a little bit differently.

 

[kfacres]

supply/ demand..

original is dead...  supply is no longer there... demand remains...

pure economics.

clone- the supply is there- the demand is not... as compared to the donor

Clone are the exact same genetically!!! How do you figure a clone is bred differently than a clone? A clone is not even bred. Its created from DNA taken from the original animal.........

the RNA can be different-- stemming from the actual recip. 

most often associated with color pattern.

So basically- a clone is something like 99.5% the exact same genetically.

why do you think clones look different? different enviroment, different color patterns, different management.

it may not make allot of sense ,but clones DO breed differently than the original sometimes ,,,the heatwaves are good examples of that

in that case: maybe the original was just a freak of nature-- and the clones breed like he SHOULD have bred? 

something to ponder.

Does that mean his offspring will breed more like the clones then?

Color Pattern?? All the heat wave clones are Black...........the monopoly clone is black..................and all 5 of the solid gold clones are all the orangish color so Im just wondering how the color pattern is most affected? Just wondering

Clones are genetically IDENTICAL to the animal they are cloned from.  The differences you see in the the clone and the animal it is cloned from are due to environmental effects.

The differences you see in calves from clones versus the original is due to the sheer number of calves that are born and the concept of probability.  There are over 20,000 some genes in the bovine genome.  When you take into account the amount of alleles at each loci (animals are not homozygous for every loci), the concept of recombination and the fact that the dam contributes 50% of the genetic material (cow "types" have evolved since the original Heat Wave was used) PLUS the environmental effects of prenatal and postnatal nutrition, you are going to see differences in calves. Chances of getting calves that are identical at all of those loci and having all of the same environmental effects are slim to none.

Think of it this way.  You can flush a cow and get 15 calves.  5 of them are the next great ones, 5 of them are dogs and the other 5 are somewhere in the middle.  Breeding is a crap shoot.  The concept of linebreeding works to increase consistency and uniformity because it increases the amount of homozygosity in the herd and therefore reinforces the concept of "like begets like".  When you are breeding animals to compliment each other you are not going to get that.  More than likely you'll end up with 5 great ones, 5 average ones and 5 dogs.  

Color pattern is due to migration of melanocytes.  Pattern types (like spotting or belts) are controlled by genetics in the sense that certain parts of the body are pigmented and some are not, but exact migration and exact pattern (how the spot is shaped or how large the belt is) is random.  Therefore the final color pattern on the body of the clone is not going to be 100% identical to the animal it is cloned from.

So would this follow suit with identical twins? I know of several sets of twins from an embryo, meaning the single egg split after it was put in the recip. The calves have had a variety of different face markings, and I always thought that identical meant IDENTICAL. The migration of the melanocytes kind of explains this then, correct?

 

[KSUwildcat2009]

Yep, that is right! It's cool stuff!!

 

[Shady Lane]

After hearing talk about slight genetic variations in clones, different markings of identical twins etc. being the effect of DNA contributed by the recip, Do similar effects occur in ET calves?

Can the recipient dam affect a colour pattern or other variables?

Do these genetic variations occur in Utero from the recipient dam carrying the clone or are we strictly talking about mitochondrial DNA from the embryo that the cloned DNA is imbedded in?

it is my understanding that yes they can be.. but then again, I am not a rocket scientist, and my degree is in helping people help the land...

You also have to consider when we say "identical" we are talking about what science says is identical, doesnt always mean that it is an exact copy.  My understanding is somewhat like Jody's, clones are considered to be 99.5% identical or something like that, so very very low probability that any genetic difference of significance will occur, but you have to leave some room for differences in the embryo that it is implanted into.  For the clone to be an exact copy the embryo would have to be an exact copy from the beginning and that doesnt happen.  But the other side is true also, most of the differences we notice between clones and the original, with the exception of markings, is purely caused by difference in environment.  Environment is where the recip affects them, recip cows have no affect on genetic material of the fetuses they carry.  So in clones any minute genetic difference you might find would be from the host embryo that the clone DNA was injected into.  I think the thing to remember here, is there is still a lot to be learned about this process.  I have heard it both ways from researchers.  Some say there is no way there is any genetic differentiation from the original, some say there is possibility for some differentiation, but it is insignificant to the point that we call them identical copies.
The reason all the clones named earlier are the same color patterned as the originals is they all have solid color patterns.  Color in clones will always be the same, where it can differ is in the markings.  Actual size and shape of markings is kind of purely by chance and how the cells split etc.

I thought I have seen or read that the markings will be in different locations, but the area of the color will always be the same...  if the clone donor has 15 in2 of white, then the clone will have 15 sq in of white... just in a different location depending on how the fetus was laying in the womb.
