本题详细解析:
Ecosystem diversity is defined as the variety and c1gt47in:nyct3 q dw2+w+ bdnabundance of different ecosystems present in a geographical area. Genetic diversity is the genetic variability within a species or population. Species diversity is the number and relative abundance of species found in a specific area. Therefore Choice C is correct.Choice A is incorrect because genetic diversity does not only refer to the type of alleles in a population but the number of different alleles in a population. Choice B is incorrect because phenotypic variation refers to differences in observable characteristics, not genetic diver2nt7i d+1c qt yw+:d3wncbn g4sity, and the definition of ecosystem diversity shown in row B is actually the definition for species diversity. Choice D is incorrect as genetic diversity does not relate to the control of the expression of genes (epigenetics) within a population and the variety of all life on Earth is the definition for biodiversity.
