| Abstract: | Objective] To explore the genetic diversity and maternal origin of Jiaxian Red cattle. Method] Using bioinformatics methods. Result] A total of 60 mutation sites was detected in the mtDNA D-loop region of 46 Jiaxian Red cattle, and 20 mtDNA haplotypes were defined. The average haplotype diversity (Hd) is 0.8530, and the average nucleotide diversity (Pi) is 0.0254, indicating that Jiaxian Red cattle have rich maternal genetic diversity. The constructed IQ phylogenetic tree shows that Jiaxian Red cattle have two maternal lineages with zebu and taurine cattle. Conclusion] Jiaxian Red cattle have rich maternal genetic diversity and two maternal origins of zebu and taurine cattle. |
