A median-joining network was produced by the network software 10.1 for eight haplotypes of native Indian chicken breeds along with reference mtDNA based on the polymorphic site of the mtDNA D-loop region (A) and complete mtDNA sequences (B). The area of each yellow circle is proportional to the frequency of the corresponding haplotype. The pink dots illustrate median vectors (mv) and the numbers on each link line represent mutated positions.
