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 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.
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.
A mechanism of darwin's proposed theory?
The mechanism is natural selection, of course.

Is ecological isolation a prezygotic isolating mechanism?
Sure is. How can one mate if an ecological barrier is erected between two biological species? Even something as simple as the time of day can be a barrier to mating.
What is prezygotic isolation?
Prezygotic isolation is a type of reproductive isolation. It ceases F1 zygote to cross mate that wards off its production.
A reproductive barrier that prevents species from mating is an example of?
a prezygotic barrier
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.
Isolating mechanisms that take effect before or during fertilization are termed?
prezygotic
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 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.
A mule is prezygotic or postzygotic?
The mule would be considered postzygotic. This is because of the usually sterile reproductive traits that are commonly associated with being a hybrid.
What is a description of the types of prezygotic barriers?
the barriers that allow for more specific sexual preferences. such as leather or whipped cream, or in some species handcuffs.
A group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate Such a ritual constitutes a type of?
Behavioral....prezygotic
