Although the size of the assembled genome increased by 29 Mb (12% of the version 4.0 genome) as a result of additional sequencing reads and better assembly, a total of 76 Mb of sequence (32% of the genome) was mapped to chromosomes with longer scaffolds and additional markers in AmelMap3 compared with AmelMap2. *The number of markers used for the assembly differs from that given in the text (1,142). Markers without accession numbers (92) were omitted. After the freeze of assembly 4.0, some markers were added and others removed from the AmelMap3, which now comprises 2,008 markers.
