Question

Continuous inbreeding leads to:

• A. Reduced fertility
• B. Reduced resistance to disease
• C. Reduction in productivity
• D. All of the above

Answer 1

The correct option is D All of the above

When inbreeding occurs excessively, the progeny suffer from what is called inbreeding depression- a phenomenon in which continued inbreeding leads to reduced fertility, reduced resistance to disease and eventual reduction in productivity, etc. When such an instance occurs, farmers mate these animals suffering from inbreeding depression with random superior animals of the same breed which immediately restores fertility and yield in the offsprings produced.
