La endogamia en la producción animal

ABSTRACT: We made a literalature review about advantages and disadvantages of using inbreeding (crossing of related individuals) directly or indirectly in animal production. The inbreeding acts in wild and domesticated animal populations reducing genetic variability, decreasing heterozygosity, and increasing the chance to inherit alleles associated with genetic defects, resulting in a reduction of the animal adaptation capacity to the environment and increasing the risk of extinction. Also has been demonstrated that inbreeding increase is associated with the average reduction of one or more economic interest characteristics in animalproduction. For this reason in conservation and breeding programs is very important have control over inbreeding to maintain the genetic variability within animal populations over time. Key words: Heterozygosity, animal breeding, selection, genetic variability. Keywords: Heterozygosity, animal breeding, selection, genetic variability.
