How can you ever be sure who has what genetics if all you can base things off of is from trying to reverse-engineer the info?
Would the sterilizing mess up the DNA, so the test would then be worthless?As others noted, you can get DNA tests done to prove whether your birds have 1 or 2 copies of the oocyanin gene through Justus Liebig University. Caution that there are problems at this time since feathers are not allowed to be shipped into Germany unless they are heat sterilized.
Okay, good to know.Yes, more difficult but not impossible
Worthless as the DNA would be damagedWould the sterilizing mess up the DNA, so the test would then be worthless?
The legs on Asils always get me. They look so sturdy, especially as compared with leghorns.
We tested heating of feathers in a normal kitchen convection oven, packed in aluminium foil and closed with sterilization tape (for dry air sterilization). If this packages are heated for 150°C for 30 min, the tape will show with color change that there is a successful sterilization. Hence, it can be written on the package "feathers, steriized". We tested DNA extracted from sterilized feathers and it was ok.
I thought that it was customs doing the esterilizationPer the guy who runs the tests in Germany, they trialed heating treating feathers and were able to extract DNA afterwards. As you may guess, temperature is important. Here is a quote from an email he sent a few weeks ago.
