Lil Wayne is expected to continue the fight against allegations that a gun on his tour bus belonged to him when he enters a New York courtroom today.

Forensics experts will be on hand to determine whether or not low copy DNA profiling can be established in a court of law.

Low copy DNA is often used to identify suspects in criminal cases by identifying them with small portions of DNA.

The New Orleans born rapper denied possession of the gun when his tour bus was pulled over in 2007.

If the Young Money front man is in fact found guilty, he could face up to three and a half years in prison.
