What is the Type of Speciation That Can Occur in an Instant

Question

What is the type of speciation that can occur in an instant with a change in chromosome number?  
A) Temporal
B) Mechanical
C) Behavioral
D) Ecological
E) Sympatric

Accepted Answer

The type of speciation that can occur in an instant with a change in chromosome number is known as sympatric speciation. This occurs when a subset of a population becomes reproductively isolated from the rest of the population due to a change in the number of chromosomes, typically through events such as polyploidy or chromosomal rearrangements. This can result in the development of a new species within a single geographic location.
