Impossible to tell

Explanation:

The prediction of the number of bands that will appear after any type of PCR amplification procedure requires the crucial information like the primer sequences as well the as the amplicon sizes used for that particular PCR.

No matter what it is autosomal or hetrozygous, the basic information is always required.
