Threats, attempts and opportunities of conserving indigenous animal genetic resources in Ethiopia

摘要: Loss of genetic diversity among animal populations occurs due to introgression, crossbreeding, inbreeding, climate change and its related factors. Therefore, the objective study was quantify threats, previous conservation attempts opportunities conserving indigenous resources in Ethiopia. The consequences introgressions include reduced survival fitness first second generations, accelerated growth rate, decreased predator avoidance behaviors increased agonistic behaviors. Inbreeding allows rare, harmful recessive alleles become expressed homozygous form, with resulting effects reduces variability performances on offspring. cause threatening adapted breeds Ethiopia is indiscriminate crossbreeding exotic germplasm. On other hand, changes, are changing their distribution patterns. Animals specially wild shifting ranges, altering phenology, changes population dynamics, some facing extinction, or have extinct.
