No they are two different species (different DNA) so they don't interbreed. Hares live above the ground wheareas rabbits live in burrows.
A male donkey and a female horse can produce a mule but a female mule doesn't produce offspring, she's sterile. The male mule can't pregnate a donkey or a horse.
No, abit like breeding a cat with a tiger, or a mink and a polecat, harvest mouse and a field mouse, why do not there dna is different. I see where you are coming from, ie liger lion/tiger
