Population genetic diversity and genetic evaluation models reveal the maternal genetic structure and conservation priority characteristics of indigenous cattle in China

The population genetic structure of domestic animals and the protection of genetic resources are major issues of concern in the field of global biology. In this study, the mtDNA D-loop sequences of 1163 Chinese indigenous cattle (Bos taurus and Bos indicus) were used to analyze their maternal origin...
