Hi Pat,
As far as I know, no one has pinpointed the genetics at play with the tigers... I also understand that the tiger pattern does not happen in any great or reliable frequency...
The thing is, my entire clutch looked this way...
I will be breeding the pair that produced these to eachother again this coming season to see what the outcome is... It could be a nice strong polygenic line trait or something else... I will find out what 2 tigers produce as soon as these little ones are big/old enough to breed...
Could be something, could be nothing... It is going to be lots of fun proving these animals out no matter what the outcome may be...
