With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.

When in a gel more Joule heat is produced than can be dissipated, the temperature in the middle of the gel is higher than at the lateral edges. This causes higher mobility of the ions in the center, resulting in an uneven distribution of the zones. The zones bend up at the two lateral sides, causing
