WebInbreeding is actually lower down the diversity of gene pool. This mean you will have genetic clones in a population when there is inbreeding. That mean this inbreed population lost the genetic diversity which is very much important for survival. For e.g. a single viral attack and entire population will be doomed.

Inbreeding increases homozygosity, which can increase the chances of the expression of deleterious or beneficial recessive alleles and therefore has the potential to either decrease or increase the fitness of the offspring.
