What type of barrier inhibits the eastern and western skunks that reproduce at different times of the year (different seasons)?

• behavioral isolation

• ecological isolation

• habitat isolation

• temporal isolation

What barrier inhibits the formation of a mule (offspring of horse and donkey that is sterile)?

• reduced hybrid fertility

• reduced hybrid viability

• hybrid breakdown

• gametic isolation

When two organisms meet in the hybrid zone and the hybrid species is more favorable than the parent species, which of the following happens to the barriers?

• Reinforcement

• Fusion

• Stabilization

• Mutations

Which of the following describes why does sympatric speciation result in more reproductive barriers than allopatric speciation?

• sympatric involves geographic barriers that inihibit interactions

• sympatric involves more interactions due to an absence of geographical barriers

• allopatric involves same location to increase interactions

• allopatric involves human interaction to generate hybrid species that is absent in nature
