I'd say your het might be homo! If not, talk about serious het markers.. I've got an amel stripe het butter who I think is pretty yellow, and she's nowhere near that yellow..
Beauties both!
The parents are definitely amels, but they are also quite hyperxanthic! As for whether the large stripe is an amel or a dark butter...I think at this point, it's anybodies guess. I can see why you call it an amel stripe, but I can also see why others think it might be a butter. As you say, next year's breeding may tell you. What are you planning to pair her with?
those amels are stunning, i would use the caramel blood.
