I have been looking for a chart that would give us a testing range for Galaxy Comet, and just realized that I have the proof in my cattery.
Mom shows Galaxy Star and is too old to hide the Halloween 2016 LE eyes.
Dad is a 2016 Halloween starter
Kitten shows Galaxy Comet which cannot come from Mom.
This proves that dad hides Galaxy Comet
Mom is a 2016 Halloween starter
Dad shows Galaxy Star
Kitten shows Morning Glory, Which is known to be dominant to Galaxy Star
This proves that Mom hides Morning Glory
Mom hides Morning Glory
Dad hides Galaxy Comet
Kitten shows Morning Glory from mom and hides Galaxy Comet from dad
Galaxy Comet is therefore recessive to Morning Glory
