The ancestral alleles associated with the phase 1 release where generated using two different processes.
The SNP ancestral alleles were derived from Ensembl Compara release 59. The alignments used to generate them can be found in the phase1/supporting directory.
The indel ancestral alleles were generated using an separate process
The deletions should not have any ancestral alleles
