foreach ($bd_tab_locus as $bd_locus_name => $bd_tab_allele){
echo "locus BD = ".$bd_locus_name."----allele 1 bd =".$bd_tab_allele['allele_1_bd']."----allele 2 bd =".$bd_tab_allele['allele_2_bd']."<br>
Locus file = ".$bd_locus_name."----allele 1 file = ".$file_locus[$bd_locus_name]['allele_1']."----allele 2 file =".$file_locus[$bd_locus_name]['allele_2']."<br><br>";
