Only seven brown-and-white pandas, originating from the Qinling mountain range, have been documented. The discovery of the missing DNA sequence in Bace2 provides insights into the genetic basis behind the brown pandas' coloring.
Previous studies have indicated the separation of Qinling and Sichuan pandas hundreds of thousands of years ago. By analyzing genomic data from brown pandas like Qizai and comparing them with black-and-white pandas, researchers uncovered notable genetic disparities.
