Responses
A The two species are not attracted to one another anymore.The two species are not attracted to one another anymore.
B The two species can breed and all offspring will be Abert species.The two species can breed and all offspring will be Abert species.
C The two species of squirrel can interbreed and produce fertile offspring.The two species of squirrel can interbreed and produce fertile offspring.
D The two species of squirrel will no longer be able to interbreed and produce fertile offspring.
Question 1: The type of speciation repressed by the Grand Canyon squirrels is allopatric speciation.
Question 2: If the Kaibab and Abert squirrels were introduced, the conclusion that can be made is that the two species can interbreed and produce fertile offspring.
Question 1: The type of speciation that is repressed by the Grand Canyon squirrels is allopatric (D).
Question 2: If the Kaibab and Abert squirrels were introduced, the conclusion that can be made is that the two species of squirrel can interbreed and produce fertile offspring (C).
To determine the type of speciation repressed by the Grand Canyon squirrels, you would need to study their geographic distribution and determine whether they are separated by a physical barrier, such as the Grand Canyon itself. If the squirrels are separated by a physical barrier that prevents gene flow between populations, then it would be considered allopatric speciation (option D).
Regarding the interbreeding of the Kaibab and Abert squirrels, if they were introduced, you would need to know whether they are capable of producing fertile offspring. If the two species can interbreed and produce fertile offspring, it would suggest that they are not reproductively isolated and can potentially merge into a single species (option C). On the other hand, if interbreeding results in infertile or inviable offspring, it would indicate reproductive isolation and the continued existence of two separate species (option D).
