Hi all.

As a biological science major ( among others ), writing punnett squares is an all too common activity. Admittedly, I write them less frequently than I used to but I'm sure you understand. For those who might not know, a 'Punnett Square' is simply a tool to help you understand how alleles are passed to the next generation. It enables you to follow each parental allele as it could get passed to the next generation.

In order to 'perl-ize' ( trademark pending ), I wrote the following simple program that will quickly calculate the resulting genetic model: 


#!/usr/bin/perl -w
use strict;

my $numTop;
my $numSide;
my @top;
my @side;

print "Number of pairs for top of punnett square:";
chomp( $numTop = <STDIN> );

for( my $x = 0; $x < $numTop; $x++ )
{
  print "Enter pairs ( xx ): ";
  chomp( $_ = <STDIN> );
  push @top, $_;
}

print "Number of pairs for side of punnett square:";
chomp( $numSide = <STDIN> );

for( my $y = 0; $y < $numSide; $y++ )
{
  print "Enter pairs ( xx ): ";
  chomp( $_ = <STDIN> );
  push @side, $_;
}

for( my $i = 0; $i < @top; $i++ )
{
  for( my $j = 0; $j < @side; $j++ )
  {
     print "$top[$i]" . "$side[$j]\n";
  }
}

If you can help improve the design, I would be appreciative.

Thanks,
