Matrix estimate of genetic divergence (%) between nucleotide sequences (374 nt) of NDV strains.

*Intragenotype or intrasubgenotype: Maximal value of Nucleotide genetic divergence. **Intergenotype: Minimal value of genetic divergence. ***Class I. All results are based on the pairwise analysis of 61 NDV sequences including the 4 MG isolates (genotype XI). The nucleic acid analyse were conducted using Kimura 2-parameter method in MEGA4 [31], [78]. All positions containing alignment gaps and missing data were eliminated only in pairwise sequence comparisons (Pairwise deletion option). There were a total of 374 nt positions in the final dataset.
