Genetic drift does not occur if the population is homozygous and breeding true.

This is where jazz would laugh. If you listened, there is a range in our fiber strength. That is "required" variance. You have to have a good level of monitoring to assure you do not go below desired thresholds. You are simply going to have to do more homework or go back and read jazz710 here or on IV. His expertise is in genetic modification, but hey if you prefer mojo's pedigree and logic, have at it. Words to consider from jazz, or completely dismiss.....

"When push comes to shove, once the silkworms reach homozygosity, which I'm sure that ours have and is easy to check/achieve with the right checks in place, that they will do as nature has programmed them to do: Make fiber. That's the real benefit of the animal system vs. yeast/bacteria. The worms output our raw product, which can (with slight modifications) be treated like normal silk for all intents and purposes. The vat producers can do all of the optimization that they want, but the fact of the matter is that their raw product is protein in solution. While it can be artificially spun into a product, they have to put a lot more into their system than we do cost-wise. We have the worms, we're tweaking the silk processing parameters, and at that point, our main input to the system is mulberry leaves or pellets. "

Now if you want to exaggerate drift as a bigger issue than it is.....embrace it.
