The following contact has committed to helping others within their own breed with information regarding Merle testing.
Zeca - Ma+/m - 262/m
NOTE - Dr. Clark tested Zeca as Ma/m but I knew there was too much expression of a Merle pattern so tested through Vemodia to confirm Ma+
Eagle - Mh/m - 274/m, S/S
Belle - Mh/m - 274/m, S/*
Eagle is Belle's dam.
Eagle's Mh was passed to her offspring at the same length of 274 bp.
