Practice Questions

Question 1

Which of the following scenarios best describes a situation where hybrid sterility would be observed?

Question 2

In a population of insects, a subset begins to feed on a new host plant. Over several generations, these insects develop a preference for mating only with others that feed on the same host plant, even though they are in the same geographic area. This scenario is a strong example of:

Question 3

A group of finches colonizes a newly formed volcanic island. Over many generations, the descendants of these finches adapt to various ecological niches on the island, developing different beak shapes for specialized diets (e.g., seed-eating, insect-eating, fruit-eating). This evolutionary pattern is best described as:

Question 4

Which of the following is the most significant factor in initiating allopatric speciation?

Question 5

Two closely related species of orchids live in the same tropical rainforest. One species is pollinated exclusively by a specific type of bee, while the other is pollinated by a particular species of moth. This difference in pollinators prevents gene flow between the orchid species. This is an example of which type of reproductive isolating mechanism?
