Hi monks,i want to bring to hashes in a subroutine but subroutine doesn't recognize one of them.please help me.

sub versatility{

my(%genome1,%genome2)=@_;

for my $key (keys %genome1) {
   
my @genome1=$genome1{$key}=~ /(\d+)/g;
my @genome2=$genome2{$key}=~ /(\d+)/g;

    
     my $m=($genome1[1]-$genome2[1]);
     my $n=($genome1[0]-$genome2[0]);
     if( $n==0){
print "number of occurance for $key in two genome are same\n";}       
else{
my $slope=$m/$n;
print "domain versatility= $slope\n";}
  
}
}
