Beautiful photos you have :cheers:
You need motley parents, or parents carrying the recessive motley trait (het motley) to have motley offspring. The motley trait can be bred into any color corn, although not all colors have been done yet. The motley trait appears to have a hypo like effect & lightens the colors somewhat. Brightly colored amel motleys (lacking any white) are called Sunglows – pic of one on my avatar. Quite beautiful !!
The motley trait has a variable appearance & can be exhibited as pin-striped, q-tiped, zippers, hurricane. It can at times mimic the stripe trait, with the motley pattern appearing to be head to tail stripes - although experts can tell the difference between the true stripe & the mimic by the width of the pattern.
Motley & stripe pattern traits appear to reside at the same locus (location on a chromosome), with motley recessive to normal (wild type), and stripe recessive to motley. There was much conversation about that topic earlier this year, I’ll leave it at 1 sentence, lol
Photo of a Sunglow Motley attached - he has a typical dot - dash - dot motley pattern.
