Biodiversity is measurable at three levels: - ANSWER Genetic level= variability within species Species level= variability among species Ecosystem level= variability among ecosystems Three domains of life: - ANSWER Archaea, eukarya and bacteria Population - ANSWER interbreeding group of individuals. Populations exchange genes Purpose variability within a population - ANSWER 1. some genetic variants have advantages over others 2. natural selection can act on variation What if popula...

Population - ANSWER A group of individuals that belong to the same species and live in the same area Purpose of variability within a population - ANSWER - some genetic variants have advantages over others - natural selection can act on variation (if needed) genetic divergence - ANSWER the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often after the populations have become reproductively isolated for some ...
