Aha, species is one of the most problematic and contentious definitions of the scientific community. Generally, each species has a distinct gene pool and can not produce viable offspring by mating. A mule (the offspring of a male donkey and a female horse) is a well known exception to this rule, and while viable, is usually sterile. However, other sterile hybrids are known, especially in birds and plants, where they are often called a 'mule' as well.
It has a set of genes in the animal that help it reproduce and adapt to its environment to help it live.
any species pretty much but here are two panda elephant
You are.
a hybrid
sterile
a species..i think..:T
they reproduce to give sterile offspring example Tigon (lion and tiger)
They can be formed by evolution: A species can't survive in it's environment so it evolves into a more adapted species Two different species can mate: A new species can appear from the offspring of two different species.
The offspring are usually sterile.
A hybrid is the offspring of two different species, in many cases animals with a differing amount of chromosomes. Examples would be mules (horse and donkey), ligers (tiger and lion), wolfdogs...
A hybrid
The offspring of different animals are known by different names- for example the oppsring of a Lion is called a cub, that of a cow is called a calf and so on.
Twins.
They are different species. Feline and a canine animals can not mate, and produce offspring.

If it were possible - The new offspring would be classified under the male 'parent' animals bloodline.

If the two species are even able to produce offspring, then the offspring would be a hybrid. For example, a donkey and a horse breed to make a mule. Due to the definition of "species," the offspring would either be infertile, inviable or both.
They can be formed by evolution: A species can't survive in it's environment so it evolves into a more adapted species Two different species can mate: A new species can appear from the offspring of two different species.
because a mule comes from a female horse and a male donkey, which are two different species, the mule will be sterile. This is because it is a general rule that if two animals of different species have offspring, their offspring will not be able to reproduce
offspring recieve different combinations of genes from each parent.
If their karotypes (number of chromosomes) don't match or if they are bred and fail to produce offspring or the offspring are infertile.
