In its common modern meaning, a mule is the offspring of a male donkey and a female horse, which is classified as a kind of F1 hybrid. The reverse, the offspring of a male horse and a female donkey, is called a hinny. The term "mule" (Latin mulus) was formerly applied to the offspring of any two creatures of different species - in modern usage, a "hybrid".

The mule, easier to breed and usually larger in size than a hinny, has monopolized the attention of breeders. The chromosome match-up more often occurs when the jack (male donkey) is the sire and the mare (female horse) is the dam. Sometimes people let a stallion (male horse) run with a jenny (female donkey) for as long as six years before getting her pregnant. Mules and hinnies are almost always sterile (see fertile mules below for rare cases). The sterility is attributed to the differing number of chromosomes of the two species: donkeys have 62 chromosomes, whereas horses have 64. Their offspring thus have 63 chromosomes which cannot evenly divide.

A female mule, called a "molly", that has estrus cycles and can carry a fetus, can occasionally occur naturally as well as through embryo transfer. The difficulty is in getting the molly pregnant in the first place.

RE:
Is there male and female in the Mule race?

Yes, there are male and female mules (which are a species, btw, not a race). They have reproductive organs, they just do not produce viable sperm or eggs and are therefore sterile.
Edit: The below poster is correct. I mis-typed. They are a sub-species, not a full species since they cannot reproduce. They still aren't a race. There is no "race" in biology, that is a social construct.

Yes,but being a hybrid ( a cross between a donkey and a horse) they are usually sterile,although a baby mule was just recently born in Colorado to a Molly ( female mule) and a Jack ( male donkey.)

If they can't reproduce, how can you call them a species? A species breeds only within the group. Otherwise horses and donkeys would be the same species. There are animals that can interbreed artificially (meaning that it doesn't happen in the wild) because of natural geographic isolation, but their offspring aren't sterile.

there are both malke and female mules, however, in most cases ( like 999 out of 100) the mule is sterile.

No,mules are sterile(hybrid sterility)

The male is a Jackass, the female is a Hinny.

no they cannot reproduce they are the result of a horse and a donkey mating
