=head1 NAME

Bio::PopGen::PopulationI - Interface for Populations

=head1 SYNOPSIS

  # Get Bio::PopGen::PopulationI object somehow, like
  # from Bio::Population::Population

  print "name is ", $population->name(), "\n";
  print "source is ", $population->source(), "\n";
  print "description is ", $population->description(), "\n";

  print "For marker $markername:\n";
  foreach my $genotype ( $population->get_Genotypes(-marker => $markername) ) {
      print "Individual ", $genotype->individual_id, " genotype alleles are ",
      join(',', $genotype->get_Alleles()), "\n";
  }
  # get a marker with allele frequencies calculated from the population
  my $marker = $population->get_Marker($markername); 
  my %af = $marker->get_Allele_Frequencies;
  foreach my $allele ( keys %af ) {
      print "$allele $af{$allele}\n";
  }

=head1 DESCRIPTION

This interface describes the basics of a population.  One can use this
object to get the genotypes of specific individuals, only those
individuals which have a certain marker, or create a marker with
allele frequency information.

=head1 FEEDBACK

=head2 Mailing Lists

User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to the
Bioperl mailing list.  Your participation is much appreciated.

  bioperl-l@bioperl.org                  - General discussion
  http://bioperl.org/wiki/Mailing_lists  - About the mailing lists

=head2 Support 

Please direct usage questions or support issues to the mailing list:

I<bioperl-l@bioperl.org>

rather than to the module maintainer directly. Many experienced and 
reponsive experts will be able look at the problem and quickly 
address it. Please include a thorough description of the problem 
with code and data examples if at all possible.

=head2 Reporting Bugs

Report bugs to the Bioperl bug tracking system to help us keep track
of the bugs and their resolution. Bug reports can be submitted via
email or the web:
