By contrast, outbred populations are used when identical genotypes are unnecessary or a population with genetic variation is required, and these rats are usually referred to as stocks rather than strains. WebMD Symptom Checker helps you find the most common medical conditions indicated by the symptoms nausea or vomiting and red (bloodshot) eyes including Allergic reaction, Food poisoning, and Glaucoma. [2] Laboratory rats are frequently subject to dissection or microdialysis to study internal effects on organs and the brain, such as for cancer or pharmacological research. Are you a fan of albino rats? They tend to stick close to walls and corners — surfaces their whiskers can feel. Because albinos can have weak eyesight, they depend on their senses of smell, hearing, and touch to help them navigate their environment. The shaking rat Kawasaki (SRK) is an autosomal recessive mutant rat that has a short deletion in the RELN (Reelin) gene.

Aside from the transparent cornea at the front of the eye, the eyeball is encased by a tough, white, opaque membrane called the sclera.
