A. Sympatric Speciation is Behavioural isolation ;Sympatric and Allopatric Speciation is Geographic isolation;Allopatric Speciation is Polyploidy
B. Sympatric Speciation is Temporal isolation ;Sympatric and Allopatric Speciation is Pluripotency;Allopatric Speciation is Geographic isolation
C. Sympatric Speciation is Polyploidy ;Sympatric and Allopatric Speciation is Behavioural isolation;Allopatric Speciation is Geographic isolation
D. Sympatric Speciation is Geographic isolation ;Sympatric and Allopatric Speciation is Behavioural isolation;Allopatric Speciation is Polyploidy
参考答案: C
本题详细解析:
Choice C is correct because polyploidy is common in sympatric speciation, behavioural isolation is common to both, and geographic isolation is only part of the process of allopatric speciation. Choice A is incorrect because although behavioural isolation can lead to sympatric speciation, geographic isolation cannot. Choice B is incorrect because although temporal isolation can lead to sympatric isolation and geographic isolation can lead to allopatric isolation, pluripotency refers to the capacity of a cell to divide and differentiate to produce almost any cell of the body except extraembryonic cells, such as those in the placenta. Choice D is incorrect because geographic isolation is not part of the process of sympatric speciation.
