Genetic divergence between Pallid and Common SwiftsRANDI E. and BOANO G.
Abstract:We have estirnated the average mitochondrial DNA nucleotide divergence between Cornmon and Pallid Swift (Apus apus and A. pallidus) using the restriction fragment technique. These two species share 63% restriction fragrnents, which corresponds to about 2% sequence divergence. The study of rnitochondrial DNA sequence divergence may be useful to resolve the unclear phylogenetic relationships among rnany closely related species of swifts.
