Fig. 1.
Nucleotide of the haplotype sequences in buffalo. Dots (.) denote identity with the Buffalo_hap1. Nucleotide substitutions are denoted by different letters. Missing information is demonstrated by a blank (-). The same hereinafter.
Fig. 2.
Network profile of 8 buffalo haplotypes of the CSN1S1 gene. The links are labeled by nucleotide positions to designate transition or transversions. Dotted line represents the haplotype generated from skipping exon 6 after transcription. The CSN1S1 haplotype frequency in buffalo was proportional to the circle area. Samples from river and swamp buffalo are indicated by white and black color, respectively.
