Question

question 6 (mandatory) (2 points)
which type of reproductive isolation occurs when there are differences in the size or shape of reproductive parts that may prevent interbreeding?
ecological isolation
temporal isolation
behavioral isolation
mechanical isolation
question 7 (mandatory) (2 points)
true or false? if a geographic barrier such as the great wall in china arises that interrupts gene flow between two populations, then allopatric speciation has occurred.
true
false

Explanation:

• Question 6:
• Ecological isolation: Occurs when species occupy different habitats within the same area.
• Temporal isolation: Happens when species breed at different times.
• Behavioral isolation: Results from differences in mating behaviors.
• Mechanical isolation: Arises due to physical incompatibility of reproductive organs. Since the question mentions differences in size or shape of reproductive parts preventing interbreeding, this is mechanical isolation.
• Question 7:
• Allopatric speciation is speciation that occurs when a population is divided by a geographic barrier, which interrupts gene flow. The Great Wall acting as a geographic barrier interrupting gene flow between two populations fits the definition of allopatric speciation.

Answer:

• Question 6: Mechanical isolation
• Question 7: True
