Prevent loss of Genetic Diversity and Inbreeding
The knowledge of parentage provides one with information about the origin and identity of the parents.
The variations and changes in the genes of the progeny of the parents can also be understood by the knowledge of the parentage.
Population of wild endangered species can benefit from the knowledge of parentage as this can help in prioritizing original gene material, avoid inbreeding incidents , important tool to manage cross between species hence aiding in the prevention of genetic diversity and loss of population.
In zoos, inbreeding is very common due to small populations which can lead to an increase in homozygous populations instead of heterozygous ones. Decrease in heterozygous populations implies decrease in genetic variability.
∴ Knowledge of parentage in zoos can help with that.
