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.
How do postzygotic isolating mechanisms reinforce prezygotic ones?
Postzygotic isolating mechanisms reduce the fitness of hybrid offspring, adding an additional barrier to prevent interbreeding between different species. This reinforces the effectiveness of prezygotic isolating mechanisms by ensuring that even if mating does occur, the resulting hybrids are less likely to survive and reproduce, further preventing gene flow between the species.
What is a prezygotic mechanism?
prezygotic or postzygotic
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.
What is an isolating mechanism and how does it create a situation leading to speciation?
An isolating mechanism is any factor that prevents two populations from interbreeding, leading to reproductive isolation. This can be due to geographical barriers (such as mountains or rivers) or differences in behavior, mating rituals, or habitat preferences. Over time, these isolated populations may accumulate genetic differences, leading to the formation of new species through the process of speciation.
Why do geographical isolation is not regarded as a reproductive isolating mechanism?
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.
Two species breeding at different times describes what isolating mechanisms?
Temporal isolation: Individuals do not mate because they are active at different times. This may be different times of the day or different seasons. The species mating periods may not match up. Individuals do not encounter one another during either their mating periods, or at all. Source:Wikipedia: Isolating mechanisms
Which mechanism do the different organism populations found across the tundra exemplify?
Species diversity :)
Why did the dome come down in under the dome by Stephen King?
In Stephen King's novel "Under the Dome," the dome comes down due to the actions of an alien species testing the effect of isolating a town from the outside world. The dome serves as a way for the aliens to observe and study human behavior in an enclosed environment.
What influence did speciation have on Darwin's development of Natural Selection?
The influence of providing an explanatory mechanism for what was obvious to Darwin; species arose and species went extinct.
What is one limitation of the morphological species concept?
There is no known mechanism for the introduction of new genetic material.
What type of tortoises can live outside?
Depends on the species
