Which of the following is the best definition of sympatric speciation?

Consequently, what is the definition of sympatric speciation quizlet?

sympatric speciation. The formation of a new species as a result of a genetic change that produces a reproductive barrier between the changed population (mutants) and the parent population. No geographic barrier is present.

Similarly, what is sympatric speciation and give an example? The hawthorn fly is an example of sympatric speciation based on a preference of egg-laying location. Another example of sympatric speciation in animals has occurred with orca whales in the Pacific Ocean. There are two types of orcas that inhabit the same area, but they don't interact or mate with each other.

Correspondingly, what is the best definition of speciation?

Definition of Speciation Speciation is a process within evolution that leads to the formation of new, distinct species that are reproductively isolated from one another. Reproductive isolation leads to reinforcement of the distinction between species through natural selection and sexual selection.

Which of the following does sympatric speciation involve?

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.
