In the late 1990s the Finnish Yorkshire pig population was threatened by a genetic defect which spread at an alarming rate and led to infertility. The defective KPL2 gene in porcine chromosome 16 caused pig spermatozoa to be short-tailed and immotile. The recessive genetic defect did not cause any other symptoms in the pigs.
