Abstract
Cichlid fishes compose an astonishingly large number of species and fonned species flocks in recordbreaking time. To facilitate efficient genome scans and comparisons of cichlid genomes, we constructed a medium-density genetic linkage map of microsatellite markers of Astaloliklpia burloni. The mapping cross was derived from two inbred laboratory lines to obtain F2 progeny by intercrossing. The map revealed 25 linkage groups spanning 1249.3 cM of the genome (size ~950 Mb) with an average marker spacing of6.12 cM. The seven Hox clusters, ParaHox Cl, and two paralogs of Pdgfrf!> were mapped to different linkage groups, thus supporting the hypothesis of a teleost-specific genome duplication. The A. burloni linkage map was compared to the other two available maps for cichlids using shared markers that showed conservation and synteny among East African cichlid genomes. Interesting candidate genes for cichlid speciation were mapped using SNP markers.
