thanxWhat is an example of reproductive isolation?
Prezygotic isolation mechanisms (before fertilization):


Behavioral - organisms of the same species are unable to recognize mating rituals (i.e., pheromones)


Temporal - mating occurs in different times of day or seasons


Mechanical - ';when the 'parts' don't fit';





Postzygotic isolation mechanisms (after fertilization):


Hybrid Sterility - when the organism is unable to reproduce (i.e., the mule)


Hybrid Inviability - when the zygote is unable to develop and naturally aborts (misscarriage)What is an example of reproductive isolation?
preventing fertilization.. basically organisms have a barrier such as unfavored genes that don't allow them to mate.
