This is an example of sympatric speciation via polyploidy, as the offspring has a different number of chromosome sets than either parent species and is therefore unable to mate with them. Allopatric speciation is the formation of a new species due to geographical isolation, while disruptive selection and character displacement involve selection for different traits within a population that can result in speciation over time. A species cluster is a group of closely related species that share a recent common ancestor.
