Key Findings
Strongest Dimorphic Changers
Ear Flare is by far the largest difference in the dataset. Females flare dramatically wider at 79° vs male 44°. This is a primary dimorphic indicator in the data.
Bizygo to Bigonial at +17.2% male is the strongest bone dimorphic signal. Males have a significantly squarer jaw relative to cheekbone width.
Lower Third being 8.4% larger in females shows females have a proportionally longer lower face relative to males in this breed.
Moderate Dimorphic Signals
Middle Third dominance in males (+5.1%) suggests males carry more facial mass in the midface.
Canthal Tilt is steeper in males (+5°), giving male Ragdolls a more angular eye appearance.
Mouth to Nose being higher in females suggests a wider mouth relative to nose width in females.
Weak or Negligible Signals
ESR Chin to Philtrum, and Maxilla Width show minimal divergence and are non dimorphic features in this breed.Summary
- Squarer jaw relative to cheekbones
- Broader, taller midface dominance
- Tighter ear set
- Steeper canthal tilt
- Wider taller nose
Female Ragdoll facial dimorphism is defined by:
- Dramatically wider ear flare
- Longer lower face
- Wider mouth relative to nose
- Slightly wider maxilla
- More uniform facial thirds
I will also make a whole cat graph as i got interested in cat facial ratios from brev (Video Inserted)
