| gallus gallus aggrecan gene-based phylogenetic analysis of selected avian taxonomic groups. | mitochondrial dna (mtdna) sequences remain the most widely used for phylogenetic analysis in birds. a major limitation of mtdna sequences, however, is that mitochondria genes are inherited as a single linkage group. here we describe the use of a 540-bp dna sequence corresponding to the g3 domain of gallus gallus nuclear aggrecan gene (agci) for phylogenetic analysis of the main groups of galliformes including phasianidae, numididae, and odontophoridae. we also included species from cracidae and ... | 2005 | 16011000 |
| how sedentary are greywing francolins (francolinus africanus)? | phasianids are considered to be sedentary birds with limited dispersal so that populations may be expected to show genetic isolation by distance. to test this, we examined genetic variability in 618 greywing francolins (francolinus africanus) at 24 localities over a 1,500 km(2) area. we subdivided the samples to measure genetic population structure among localities separated by 6-60 km, and among coveys separated by 0.1-6 km. thirteen of 30 (43%) allozyme loci were polymorphic, and heterozygosit ... | 1992 | 28569007 |
