Is it possible to use perl code to find the total number of positions where they differ and where they are alike?

Of course.

Here is one straight forward approach:

#!/usr/bin/perl my ($a, $b, $c) = qw (AAATGCCTT AAAAGCGTC AAAGGCGTC); my ($similar, $dissimilar); for (0 .. length($a)-1) { if (substr($a,$_,1) eq substr($b, $_, 1) and substr($b, $_, 1) eq +substr($c, $_, 1)) { print "MATCH"; $similar ++; } else { print "NO MATCH"; $dissimilar ++; } print " at position $_\n"; } print "There were " . $similar . " similar and " . $dissimilar . " dis +similar.\n";
