∙ 12y agoThere are a few possibilities:
Sometimes the organs used in breeding simply don't fit together
Sometimes the methods used by the male to attract the female don't register with the female as she doesn't recognise them
Sometimes the different species are "on heat" at different times in the year, and so would miss the crucial stage at which they can reproduce.
Two different species interbreeding always produce infertile offspring though, so it's not really advantageous to them!
Too much genetic differences between two species prevents any offspring. For example, in humans and chimps the difference in the number of chromosomes prevents cross breeding. Humans have 23 and chimps have 24 which make them incompatible otherwise ape men would exist today.
Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between populations
What is the most important factor that holds a gene pool together and prevents speciation?
gene flow
Polyploid speciation is perhaps the fastest form of speciation because it results in immediate?
reproductive isolation
What is speciation ?
the formation of species
When a new species arises from natural selection this is called?
I will assume the word you are looking for is speciation. Perhaps adaptive speciation to be precise.

Why do geographic isolation cause speciation?
It prevents the two populations from interbreeding. :) -Apex-
Why does geographic isolation cause speciation (Apex)?

What is the most important factor that holds a gene pool together and prevents speciation?
gene flow
If a population becomes isolate from other populations of the same species and then genetic divergence occurs that prevents them from breeding with other populations what is it called?
It is called speciation.
Speciation caused by change in the course of a river is an example pf divergent speciation?
Allopatric speciation.
Types of Speciation?
sympatric , allopatric and parapatric speciation
What prevents speciation from occurring in sympatric populations?
Gene flow between populations can hinder the development of genetic differences necessary for speciation. Additionally, strong environmental pressures favoring specific traits in a population can limit genetic variation and prevent the emergence of distinct species. Lastly, hybridization between different groups can also counteract speciation in sympatric populations.
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
Why does polyploidy not cause speciation or even be associated with speciation?
Actually it is.
Complete reproduction isolation is evidence that what has occurred?
speciation
Home of the independent response to separation?
if you are referring to the the worksheet the evolution of living things from the textbook holt science and technology, the answer is speciation
