=head1 NAME

Bio::PopGen::IndividualI - An individual who has Genotype or Sequence Results

=head1 SYNOPSIS

  # Get a Bio::PopGen::IndividualI somehow
  # test if it has alleles/genotypes for a given marker
  if( $ind->has_marker($markername) ) {
  }
  # get the unique id
  print $ind->unique_id, "\n";

  # get the number of results (genotypes)
  print $ind->num_results;

=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.

=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.
