The usefulness of maternally inherited genetic markers for phylogeographic studies in village chicken

Abstract

Phylogeography plays a major role in understanding micro and macroevolutionary processes dealing with evolutionary interpretations of geographical distribution. This field integrates information from molecular genetics, population genetics, demography, and phylogeny for the interpretation of the geographical distribution of lineages. The full mtDNA sequence and W chromosome polymorphisms were exploited to assess the usefulness of two maternally-inherited genetic markers for phylogeographic studies of village chickens. We studied 243 full mtDNA sequences from three countries (Iraq, n=27; Ethiopia, n=211; and Saudi Arabia, n=5) and a 13-kb fragment of the W chromosome from 20 Iraqi and 137 Ethiopian female chickens. The results show a high level of genetic diversity for the mtDNA within and among countries as well as within populations. On the other hand, sequence analysis of the W chromosome shows low genetic diversity both within and among populations. Six full mtDNA haplogroups (A, B, C1, C2, D1, and E1) were observed and 25 distinct W haplotypes. The results support the effectiveness of full mtDNA sequences but not the W chromosome in tracing the maternal historical genome background with, however, weak within a country phylogeographic signal.
