A. Natural selection. B. Genetic drift. C. Gene mutations. D. Gene flow. 相关知识点: 试题来源: 解析 C。解析:种群内的遗传变异最初是由基因突变(Gene mutations)引起的。A选项自然选择是对已有的变异进行筛选而不是产生变异的初始原因。B选项遗传漂变是对已有变异的随机改变而不是产生变异的源头。D选...
There are four genetic forces of evolution that result in the formation of a new species over time. These forces are natural selection, mutation, gene flow, and genetic drift.Answer and Explanation: Natural selection and genetic drift are similar in that they both result in a change in the ...
Answer to: Explain how mutations, natural selection, genetic drift, and gene flow all work together to create and maintain genetic variation. By...
(2) Could we find genetic basis for local adaptation? (3) What extent of genetic erosion is potentially associated with the long-term mass rearing? and (4) Could natural selection maintain the gene pool of wild populations upon the release of artificially bred populations? Through population gen...
Although many studies confirm long-term small isolated populations (e.g. island endemics) commonly sustain low neutral genetic variation as a result of genetic drift, it is less clear how selection on adaptive or detrimental genes interplay with random forces. We investigated sequence variation at ...
Part 1: Natural Selection Exercise—Generation 1 This exercise illustrates the effect of natural selection on populations of predators and prey. Students, in groups of four, will represent predators, each with a different adaptation for capturing their prey. The prey will consist of different species...
