Question

• A. They belong to the species Canis lupus
• B. They are interfertile
• C. They belong to the same breed
• D. Inbreeding leads to sterility in the offsprings

Answer 1

Answer: (C), (D)

Inbreeding leads to sterility in the offsprings

All breeds of dogs belong to the species Canis lupus.They are interfertile i.e. they can interbreed even though they all belong to different breeds. Since, all breeds of dogs belong to the same species, the offsprings produced by them will be fertile (able to reproduce). Inbreeding will lead to inbreeding depression but not lead to sterility in most cases.
