Which occurrence is an example of sympatric speciation?
A possible example of sympatric speciation is the apple maggot, an insect that lays its eggs inside the fruit of an apple, causing it to rot.
What is an example of sympatric speciation in plants?
Sympatric speciation is more common in plants. For instance, parent plants produce offspring that are polyploid. Another example is the rare sympatric speciation in animals — the divergence of resident and transient Orca in the northeast Pacific. Groups of orcas living in the same habitat do not interbreed.
Which is an example of sympatric speciation quizlet?
Some animals and plants appear to have diverged while living side by side—a process called sympatric speciation. One of the best examples of sympatric speciation can be found in Lake Apoyo, which formed a crater of an extinct volcano in Nicaragua.
What leads to sympatric speciation?
Sympatric speciation occurs when populations of a species that share the same habitat become reproductively isolated from each other. This speciation phenomenon most commonly occurs through polyploidy, in which an offspring or group of offspring will be produced with twice the normal number of chromosomes.
What is and give an example of allopatric speciation and sympatric speciation?
Explanation: Allopatric speciation occurs when a geographical barrier, like a river, mountain, or canyon, separates members of a population. The example with the hawks refers to sympatric speciation, where no geographical barrier exists, but speciation can still occur due to other stressors.
Is Allopolyploidy an example of sympatric or allopatric speciation?
For example, an error might occur in meiosis that produces gametes with double the DNA (Figure 4). For a diploid organism, these gametes are diploid instead of haploid. many crop plants came about via allopolyploidy. Domesticated wheat is a prime example of sympatric speciation of a fertile population.
How common is sympatric speciation?
Sympatric speciation is rare. It occurs more often among plants than animals, since it is so much easier for plants to self-fertilize than it is for animals.
Where is sympatric speciation found?
The best way to find cases of sympatric speciation is to search for closely related species in habitat ‘islands’ such as isolated lakes or small, remote oceanic islands. If these islands contain endemic sister species of mobile organisms, it is likely that those species evolved without physical isolation.
