The Malus x domestica genome v1.0  pseudo haplotype assemblies are a set of four different assemblies (primary and alternates 1, 2 and 3)  derived from the contigs of the original v1.0 assembly.  These pseudo haplotypes are intended to divde overlapping contigs in the original assembly into four different consensus sequences representing the four different haplotypes present in the apple genome.  However, these assemblies are not true haplotypes, hence the name "pseudo haplotypes".  Currently, only the primary pseudo haplotype assembly is available on GDR.  Gaps of 200,000 N's were used to space scaffolds in the assembly.  These pseudo haplotype assembles were constructed at the Instituo Agrario Di San Michelle All'Adige in collaboration with the NCBI.
