Scientists most often produce new genetic variations of organisms by causing mutations with radiation or chemicals and then selectively breeding in order to emphasize the desired traits in the new variations. The Dachshund is an example of this. By breeding two dogs with a similar mutation that caused student legs and elongated backs breeders were able to create a new variation not found in nature.

FrozenT [24]

Answer:

The mandibular canal, also referred to as the Inferior Alveolar Canal (IAC), sits within the mandible. It serves the purpose of housing the <em>inferior alveolar nerve</em> which is responsible for supplying sensation to the lower teeth.

This canal also houses the <em>inferior alveolar vein</em> - a dental vein whose function is to (with the assistance of the posterior alveolar artery) drain blood from the lower teeth and jaw.

A picture of the mandibular canal is attached.

Cheers!
