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 leads to exposure and elimination of harmful recessive genes. Inbreeding helps in the accumulation of superior genes. Through selection, less desirable genes can be eliminated, resulting in an increase in the productivity of the inbred population. Disadvantages of inbreeding
