Why do geographical isolation is not regarded as a reproductive isolating mechanism?
Wiki User

Geographical isolation is not a cause of speciation in an asexually reproducing organism because the population is self-pollinating and would be less prone to the factors which results from geographical isolation.

Which reproductive isolating mechanism is primarily restricted to animals?
The behavior isolation is the reproductive isolating mechanism that is primarily restricted to animals. In behavioral isolation, animals have unique courtship rituals such as mating dances and breeding calls.
What are isolating mechanisms?
Intrinsic mechanism is defined as an obstacle to interbreeding. Examples of intrinsic isolating mechanism includes behavioral and structural incompatibility. An example of extrinsic is geographical barrier.
The term reproductive isolation mechanism refers to?
a blockage of gene flow between populations
What are the three types of isolating mechanisms?
The word isolate has its origin in Latin where it is concerned with an island. In Physics one could isolate a region from an incoming wave, such as light, heat, sound, vibration, X-rays and so on. In Chemistry one could isolate a substance on the basis of its optical refraction, or where it was on the acid-base scale. In Biology one could isolate one species or sex from the remainder. There are more, but the general meaning is to separate.
Is bacterial endosporulation a reproductive mechanism?
No. Endosporulation is the process where bacteria encapsulates itself within an endospore - it's a form of protection against an extreme range environmental stressors. Sporulation on the other hand is the act of producing spores of the bacteria, and that IS a reproductive mechanism.
Which reproductive isolating mechanism is mostly restricted to animals?
The reproductive isolating mechanism that is mostly restricted to animals is behavioral. Reproductive isolation is also referred to as hybridization barriers.

Mechanism for when anatomical differences prevent mating?
Mechanical reproductive isolating mechanism
What type of isolating mechanism was important in the formation of Galapagos finch species?
Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.

What type of reproductive isolating mechanism is described by a situation in which female fireflies only mate with males who emit light in a particular pattern?
The form of reproductive isolation that is practiced by different species of butterflies is sexual isolation by conduct. This means that the pattern of flashing lights that the male firefly exhibits is specific to that species, and a variation will cause a female firefly to ignore them.
The term reproductive isolation mechanism refers to?
a blockage of gene flow between populations
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.
