COI (Coefficient of Inbreeding)

  • lock in desirable traits
  • produce more consistent and predictable traits in the offspring
  • establish genetic uniformity   
  1. Decreased growth rate
  2. Decreased mature weights
  3. Decreased fertility
  4. Smaller offspring at birth
  5. Smaller litter sizes
  6. Increased death rate
  7. Decreased lifespan
  8. Decreased immunity (resistance to disease is weakened)
  9. Increased genetic defects such as cryptorchidism, absence of both testes, etc.
