Backcrossing is the mating of a hybrid organism (offspring of genetically dissimilar parents) with one of its parents or a genetically related creature.
In genetics research, the backcross is beneficial for isolating (separating out) specific features in a related group of animals or plants.
Backcrosses are frequently referred to as top crosses in animal breeding.
Grading is the practice of mating average or “grade” females to a superior male and then backcrossing the female progeny to the same or comparable sire.
Final Answer:
Backcrossing is the process of crossing a hybrid with one of its parents, or an adult genetically identical to the parent, in order to produce offspring with a genetic identity closer to that of the parents.
It’s employed in horticulture, animal breeding, and the production of gene knockout organisms.
