The judge overseeing the Prince estate case has authorized genetic testing on a sample of his blood in case it's necessary to determine who's entitled to shares of the estate.
Carver County District Judge Kevin Eide on Friday granted a request by the special administrator overseeing the estate, Bremer Trust, to hire DNA Diagnostics Center to perform the genetic testing on a blood sample now held by the medical examiner's office that conducted the autopsy on Prince.
Prince's sister, Tyka Nelson said he left behind no will.

Nelson and Prince's five half-siblings decided last week that Bremer Trust should continue acting as special administrator of the musician's fortune, according to NBC News.
In his order, the judge says he's "recognizing that parentage issues might arise" in the administration of Prince's estate. He's authorized the medical examiner to release the blood sample to the testing laboratory.
Prince's estate is believed to be worth an estimated $300 million. It is rumored that he also left behind thousands of unrecorded songs.
Aside from his siblings, Prince is survived by two ex-wives. His only known child, a son named Boy Gregory, died in October 1996 at just a week old.
Prince died April 21 at his home in suburban Minneapolis. The cause remains under investigation.
