Percentage of surviving lines versus generations in crossing experiments between Poikilolaimus oxycercus species for six generations. The cross between the Vaal Rivers specimen and the Kopanang Mine and Driefontein Mine specimens were healthy; whereas the cross between the Kopanang Mine and Driefontein Mine specimens floundered by the sixth generation.
