What is the name of a rat with red eyes and white fur? - in detail
An animal displaying a white coat and red eyes is classified as an albino rat, scientific designation Rattus norvegicus. The phenotype results from a recessive mutation that disables melanin production, leaving the skin and fur devoid of pigment and exposing the blood vessels of the retina, which appear red.
Genetic mechanism
- Two copies of the albino allele (c) are required for expression.
- Homozygous individuals exhibit the characteristic lack of coloration and ocular pigmentation.
Common laboratory strains that possess this appearance include:
- Sprague‑Dawley albino rats – widely used in pharmacology and toxicology.
- Wistar albino rats – favored for behavioral and neurological studies.
- Fischer 344 albino rats – employed in aging and cancer research.
Applications
- Serve as model organisms for biomedical investigations because of their well‑characterized genome and reproducible physiology.
- Popular as companion animals due to their docile temperament and ease of handling.
Care considerations
- Sensitivity to bright light necessitates subdued illumination to prevent retinal damage.
- Susceptibility to skin lesions requires regular inspection of the fur and prompt treatment of any abrasions.
- Standard diet of laboratory‑grade rodent chow, supplemented with fresh water, supports optimal growth and health.
The term «albino rat» precisely identifies the species with the described coloration and ocular features.
