WebTherefore, a nonzero Tajima’s D implies that at least one condition for neutral evolution is violated. It is known that when Tajima’s D is nonzero, the sign of Tajima’s D gives us the interpretation of natural selection: balancing selection can result in positive Tajima’s D, and positive selection can result in negative Tajima’s D [1]. tapa rueda repuesto suzuki grand nomade
