1. Common counter-example: Horses and donkeys are considered separate species. They can produce offspring. There have been rare cases of that offspring being fertile. Not so clear.
- dragontamer 5y agoTraditionally, two members of a genus (but of different species) make infertile offspring. Two members of a species make fertile offspring. ----- This isn't a "perfect" definition, but the delineation is clear in most cases. In your case, a horse and a donkey make infertile offspring (aka: a mule), and are therefore different species but the same genus.
- 3np 5y agoWhat I'm saying is there are documented cases of mules being fertile and having healthy offspring.
