Hi,
if 0 V is applied from a DC source and we have to measure bias of an ADC, will there be any effect of wire due to voltage drop across the wire connected to the ADC input channels
 

Voltage drop across a wire can be thought of as happening when a current flows through it. If no current is flowing, there can be no voltage drop. So, if there is no potential difference across the wire (both ends are zero volts) then no current, no drop.
 

Plainly speaking unless if the there is any design error in the wire voltage never drops when passing through the wires

But as FoxyRick rightly said if the current through the segment of circuit is 0 ( i.e: in 0V condition) no drop is possible in the wire

Hi Khan 740 !
Why you think you will see voltage across your wire ? if current is zero voltage across it is zero , or perhaps if current is high too , if diagonal of wire is large , voltage drop will be insignificant .
