WebThe ‘inbred’ strain came from one cluster of eggs from a single female BSF of the Wuhan strain, whose egg weight, larval weight, and larval survival rate were not significantly different from those of Wuhan strains in the same generation. These eggs were selectively inbred for 10 generations. WebInbreeding depression is often the result of a population bottleneck. In general, the higher the genetic variation or gene pool within a breeding population, the less likely it is to suffer from inbreeding depression, though inbreeding and outbreeding depression can simultaneously occur.
Inbreeding depression is the reduced biological fitness which has the potential to result from inbreeding (the breeding of related individuals). Biological fitness refers to an organism's ability to survive and perpetuate its genetic material. Inbreeding depression is often the result of a population bottleneck.
