The History Behind Inbreeding

    Have you often wondered what brought about such poor, deformed animals(far right pictures)? Ever asked why God allowed such sad, defensless creatures to live? Or how about what type of animal gave life to anything so grotesque in nature?

Inbreeding: the reproduction from the mating of two genetically related parents, which can increase the chances of offspring being affected by recessive or deleterious traits. {Special thanks to wikipedia.com for definition}

    Many "experienced" breeders pratice "controlled" breeding to often eliminate recessive or undesirable traits. Some would prefer to call this abomination "line-breeding" or the act in which inbreeding is a "fix" to obtain desirable traits, without high risk of producing the "undesirables" that come from close inbreeding. A little-known fact though is that even when "controlled", many dangers still occur to the animals being spawned by inbred productions. Some examples of these occurances include:

  • Reduced Fertility in both Litter Size and Sperm Viability
  • Increased Genetic Disorders
  • Fluctuating Facial Asymmetry(Ex. Misaligned Jaws, Crooked Noses, Irregular Eye-Set, etc.)
  • Lower Birth Rate
  • Higher Infant Mortality
  • Slower Growth Rate
  • Smaller Adult
  • Loss of Immune System Function

    All of these are results of reduced fitness in a given population due to the breeding of closely related individuals or inbreeding depression. Inbreeding depression will in most cases lead to the constant decline and often enough, endangered species of a certain animal; this is often referred to as population bottleneck.

    To follow up with the previous paragragh, even more drastic results of this type of indecent and excessive breeding are as follows:

  • Lowered Fertility Rate In Either Gender
  • Small Litter Sizes (1-2 babies per litter) On A Regular Basis
  • Regular Appearance of Cancer In Young Offspring
  • Great Loss of Animals to One Disease.

    To end this on a much more educational note, the old saying goes "Abstinence is the key". So before starting on your journey down the breeding road, please consider the afore mentioned results of such actions when they become ignorant and unplanned. Even some of the most "experienced" breeders falter as we've already come to notice so if you truly love your pets the best thing for them is to stay pets with the help of spaying and neutering your animals at the appropriate ages. If you are ever at a loss for information in any aspect of your pets, always contact your local vetrinarian or appointed animal doctor. Remember folks, this cruelty can be prevented if even one person takes the time to notice it!

      It can then be useful to compute inbreeding, here is how:
