This topic has amused , intrigued and bewildered me for a while now....... Full disclosure have not bred with clones myself, just doing some ai ing this year to get mama cows for club calves for my kids when they get old enough in a few years.
So Heat Wave is 2-300 per straw when you can find it. HW 2 is 100 or so, and subsequent clones after him are less........ The reason being that "clones don't breed exactly true". Or something similar.
I am no idiot when it comes to genetics. I understand the minute difference genetically in clones due to mitochondrial DNA, I also understand the idea of epigenetics, that the animals environment will somewhat alter what genes get expressed to what degree. Yadda yadda
But isn't meiosis which creates the sperm, only nuclear DNA, And isn't it nuclear DNA that is extracted and used to create the clone?
In the field trial and hunt test world of labrador retrievers that I have been In for several years now there is a dog named lean Mac. A great dog that has thrown many great pups. The heat wave of the retriever world. To start with he got used A LOT. Mostly with top level females because of the stud fee, not gonna spend the increased stud fee on a POS female. So he got bred to lots of good dogs, no coincidence, he threw lots of good pups, More people sought him out, stud fee went up, now he was only getting bred to great females, so pups were more expensive only going to serious homes, more likely to have every chance to succeed...... No that he is dead and limited semen left, only elite females get him, and can name the price for the pups and they only go to SERIOUS people. So is lean Mac really that much better of stud then his sons or is it the other factors?
My theory is the same is true for heat wave vs clones (and other cloned bulls). Perhaps the reason the clones "don't breed true" is because they are not being bred to the same level of females. If I am going to shell out. 2-300 for a straw of semen, it is going to be for a flush quality cow. And because of that the are going to be differences on the cow side, plus there are going to be a few more calves per breeding to choose from so if 1-2 doesn't turn out as well not as big of deal cause. There are the one or two rock stars in the flush that people talk about. On the flip side, a thirty dollars straw of semen forma clone might get put in a more ordinary cow, and throw a nice calf, the type that made heat waves reputation to start with, but not the 50 k calf that people are seeing out of the flushes to the original that go to people that are going to do everything possible to make sure the calf works out.
So my question is do clones really not breed true, which from the biology side I see as improbable, or is it a case of higher priced semen going into higher quality cows and the resulting calves going to deeper pocketed homes?
