Two species of foxes are observed to have overlapping geographic ranges. Describe how this speciation event could have resulted from: allopatric, peripatric, parapatric, or sympatric speciation.
Homework Answers
Allopatric speciation of these foxes will be caused when the two foxes living in two different areas of Geography come and interbreed with one another to give rise to progeny with intermediate phenotype.
Parapatric species arise when some of the species living of the area move towards the peripheral zone and occupy a separate Habitat there.
Peripatric speciation arise when some of the individuals of the population move to a nearby area but it is completely different from the previous area.
Sympatric speciation will arise due to genetic polymorphism between the species of these two foxes. Initially they were not able to interbreed but afterwards they started interbreeding giving rise to progenies with new variations.

Under nearly all circumstances, postzygotic reproductive
isolation cannot evolve under the direct action of natural
selection. Instead, postzygotic isolation evolves as a by-product
of other genetic changes as proto-species diverge. In contrast,
natural selection can directly act to enhance prezygotic
reproductive isolation. Consider two species with overlapping
ranges. If hybrids between the species are less fit than pure
species individuals, females that mated with heterospecific males
would be at a selective disadvantage, because their resulting
offspring had low fitness....
