Abstract Background The honey bee is a key model for social behavior and this feature led to the selection of the species for genome sequencing. A genetic map is a necessary companion to the sequence. In addition because there was originally no physical map for the honey bee genome project a meiotic map was the only resource for organizing the sequence assembly on the chromosomes. Results We present the genetic meiotic map here and describe the main features that emerged from comparison with the sequence-based physical map. The genetic map of the honey bee is saturated and the chromosomes are oriented from the centromeric to the telomeric regions. The map is based on 2 008 markers and is about 40 Morgans M long resulting in a marker density of one every centiMorgans cM . For the 186 .
