Microphthlamia (Lethal Gene)
Microphthlamia or better known as the Lethal gene is caused by breeding a roan x roan or Dalmatian x Dalmatian together.
Studies show that there is a one in four chance of guinea pigs born from the breeding of a roan x roan or Dalmatian x Dalmatian will result in having a lethal baby. Many affected guinea pigs will die. Responsible breeders will never intentionally mate these breeds.
