Affected Breeds: Many

Research Confidence:                           Moderate confidence, strong correlation in larger studies


GG or CC - n/n - negative for known Curly genes


GA or CT - Curly/n - "carrier" status and Curly - may pass Curly on to 50% of any offspring


TAA or TT- Curly/Curly - Curly and will pass Curly on to 100% of any offspring
