Mitochondrial DNA Diversity in Commercial Lines of Laying-type Japanese Quail.

ABSTRACT: The present study aims to investigate the maternal origin and genetic diversity of laying-type Japanese quail lines based on partial sequences (453 base pairs) of a mitochondrial DNA (mtDNA) control region. A total of 478 individuals from 12 lines were sequenced and six different haplotypes with eight variable sites were identified. All haplotypes, two of which were identical to previously reported sequences, were typical for the Japanese quail (Coturnix japonica) and were distinct from those of the common quail (Coturnix coturnix) in a phylogenetic analysis including other published haplotypes. One haplotype was distributed in the majority of individuals (84.9%, 406/478) across all lines. Within each line, 72.5-100% of individuals had this predominant haplotype. The second m
