Abstract
Olfactory receptors (ORs) are expressed by olfactory sensory neurons (OSNs) and are crucial for animal survival because they are responsible for the detection of different odorants in the environment. ORs are members of one of the largest gene family in mammals, are encoded by hundreds of alleles, and display monogenic and monoallelic expression in OSNs. In the olfactory epithelium (OE), …
