Number of different species
The most common type of gerbil is the Mongolian Gerbil; However, there are many different species in the same family. The National Gerbil Society (http://gerbils.co.uk/) has a link at the top (Species) which gives descriptions of many different types of gerbils and jirds.
If two different species reproduce and have children, then these children will not be fertile. E.g, when a horse and donkey reproduce together, then the offspring is called a mule. The mule will always be infertile, as will the offspring produced by cross-breeding of species. If two different breeds reproduce, then the offspring should share the characteristics from both breeds.
