Question

Can factors that cause sympatric speciation also cause allopatric speciation? Explain.

Accepted Answer

everyone. Let's take a look at this question together. And ala Patrick speciation. The evolution of new species is brought about by geographic barriers. Meanwhile in Saint Patrick speciation. What is the most common factor that leads to species divergence? Let's recall what we've learned already about ST Pat's speciation. So we know that because Allah Patrick speciation is the evolution of new species brought about by geographic barriers. We know that ST Patrick speciation does not have those geographic barriers because in Saint Patrick speciation they occupy the same or a common region. They occupy a common region. And because of this common region there's actually less difference. The less difference in niche and resource variation, resource variation. And so because of that less difference that wouldn't really lead to species divergence. So A. And B. Are incorrect. And so looking at sea polyp Lloyd E. We know is when cells have more then one pair of chromosomes. And so because of this they actually can't reproduce with individuals that have that normal count. And so this creates something called reproductive isolation. And so reproductive isolation means that the species is unable to breed successfully with related species because of that polyp Lloyd E. Which means that it would lead to species divergence. So answer choice C. Is the correct answer. Because we know that polyp Lloyd is when cells have more than one pair of chromosomes, which means that they cannot reproduce with those that have a normal amount and that leads to that reproductive isolation. Which then means that they're unable to breed with related species and it would lead to that species divergence. So that means that answer, choice E. Is the correct answer.
