Fire is a leucistic gene, it is how you make a BLACK eyed luecistic, there is BLUE eyed luecistic group, and the BLACK eyed luecistic group. NO they are not "compatible" between the 2 groups. You can have a a pair of Fire Mojaves / Fire Lessers and can make both blue and black eyed luecistic. As far as the original post, I believe luecistic is stronger than any other gene set and will mask nearly any other genetics at play
