The mule would be considered postzygotic. This is because of the usually sterile reproductive traits that are commonly associated with being a hybrid.

The most important factor in preserving horses and donkeys as distinct biological species?
a postzygotic barrier
What is a sadle mule?
A saddle mule is a mule used for transportation or riding, were as a pack mule is a mule used solely for transporting luggage rather then people.
What is a name for a mule handler?

Which animals are sterile Donkeys or mules or can mule impregnant another mule?
Mules are sterile, a mule is the offspring of a donkey and horse, therefore sterile. A male mule can mate with a female mule, but will never get her pregnant.
A mule is not sterile?
A male mule is always sterile, however , rarely, a female mule will be able to reproduce.
Why prezygotic isolating mechanisms have an advantage over postzygotic isolating mechanisms?
prezygotic isolating mechanisms were here first and have the advantage over postzygotic because they have had a longer time to develope and get harmful genes out of their population.
What is Mechanical Isolation?
There are two types: prezygotic and postzygotic. Prezygotic barriers prevent mating from even happening. If mating does occur, postzygotic barriers reduce the chances that an offspring will survive before being born. One prezygotic reproductive barrier is mechanical isolation.
How do postzygotic isolating mechanisms reinforce prezygotic ones?
Prezygotic, of course. Unless the behavior was to expel unwanted sperm or something like that. Generally the mating behaviors prevent ( pre ) any zygotes from having any possibility of being formed.
What is one advantage of prezygotic isolation and postzygotic isolation?
Prezygotic means something that occurs before a zygote is formed or the completion of fertilization. Postzygotic is an even that occurs after the fertilization or formation of a zygote.
What is less metabolically costly to an animal prezygotic or post zygotic isolation?
Prezygotic isolation because it is usually only a result of different mating calls or times. In postzygotic isolation the organism usually dies before it has a chance to reproduce or is infertile.
What is a prezygotic mechanism?
prezygotic or postzygotic
What is thought to be essential for the formation of distinct species rather than a continnum form one from of life to another?
Reproductive isolating mechanisms are either prezygotic or postzygotic. These mechanisms ensure that species remain distinct in nature.ChaCha!answer
What are reproductive barriers?
There are two general categories of reproductive isolating mechanisms: prezygotic, or those that take effect before fertilization, and postzygotic, those that take effect afterward. Prezygotic RIMs prevent the formation of hybrids between members of different populations through ecological, temporal, ethological (behavioral), mechanical, and gametic isolation.
What is prezygotic isolation?
Prezygotic isolation is a type of reproductive isolation. It ceases F1 zygote to cross mate that wards off its production.
If a donkey and a horse mate a sterile mule may be produced?
A mule is a cross between a donkey and a horse and they are usually sterile. This is typically a female horse and male donkey and it should, theoretically, strengthen postzygotic barriers between horses and donkeys. It is a hybrid sterility type of reproductive barrier.
Hybrid inviability is an example of what kind of isolation?
postzygotic
What can keep two populations from interbreeding?
Many things. Just physical differences, a mouse is not going to breed with an elephant. Behavioral difference, such as mating dances, calls and the like. Temporal differences, such as one organism is diurnal and the other is nocturnal, or seasonal differences. These are called prezygotic barriers to reproduction. Postzygotic barriers can be as simple as a sterile match, such as horses and donkeys. Then there is just physical barriers, such as mountains and water barriers.
