Assembly 4.0 now includes 626 scaffolds that were ordered and oriented into chromosomes according to the framework provided by the third-generation linkage map AmelMap3 . Each construct was used to control the quality of the other. The co-linearity of markers in the sequence and the map is almost perfect and argues in favor of the high quality of both. Most eukaryotic genome sequencing projects are preceded by the construction of physical genetic and or cytological maps. For the honey bee genome project there was no physical map and because of the low resolution of the cytogenetic map the meiotic map was the only resource for organizing the sequence assembly on the chromosomes. The first generation map AmelMap1 comprised 541 markers on 24 linkage groups for 16 chromosomes 1 2 . Saturation was achieved by addition of 601 markers prepared
