«Detailed Physical Features»
«Coat Color and Pattern»
The Blue Dambo Rat exhibits a distinctive coat that combines a muted base hue with specific patterning. The primary pigment is a slate‑blue shade, resulting from a dilution of the standard black melanin gene. This coloration provides a uniform, low‑gloss appearance that differentiates the breed from other domestic rats.
Pattern variations are limited to a few recognized forms:
- Solid – the entire fur displays the blue base without additional markings.
- Blaze – a narrow, lighter stripe runs from the nose across the forehead, contrasting with the surrounding coat.
- Mottled – irregular patches of slightly darker or lighter blue intersperse across the body, creating a speckled effect.
Genetic inheritance follows Mendelian principles. The blue coat requires two copies of the dilution allele (dd), while the presence of the blaze or mottled patterns depends on separate modifier genes that are either dominant or recessive, depending on the lineage. Breeders aiming for a specific pattern must track these modifiers through pedigree analysis to achieve predictable outcomes.
Coat quality influences health assessments. A dense, evenly pigmented coat indicates proper nutrition and absence of dermatological issues. Conversely, patchy or faded areas may signal metabolic deficiencies or underlying disease, prompting veterinary evaluation.
«Ear Shape and Size»
