Polymorphic microsatellite DNA markers in the penduline tit, Remiz pendulinus.

To describe the exceptional mating system of the penduline tit, Remiz pendulinus, we aim to combine field observation records with DNA analysis based on polymorphic microsatellite DNA markers. Here we describe features of nine loci and their corresponding polymerase chain reaction primers. The observed number of alleles varied from four to seven and the observed heterozygosity ranged from 0.419 to 0.802. Neither of the loci is sex-linked and as linkage disequilibrium analysis showed they assort independently. Seven of the nine loci were polymorphic in the Cape penduline tit, Anthoscopus minutus.
