Hawaiian Islands that descended from the same mainland populationD. 2 or more species reproduce at dif times (pollination)E. 1genetics 2molecular biology 3evolutionary theoryF. trueG. Individuals at the upper and lower ends of the curve have higher fitness than individuals near the middleH. falseI. He did not know the source of the variation that was so central to his theory. He could not explain how inheritable traits were passed from one generation to the nextJ. 1Mutations 2Genetic ShufflingK. gene poolL. Genetic drift has less effect on large populationsM. relative frequencyN. Individuals at one end of the curve have higher fitness then individuals in the middle or at the other endO. false/falseP. The allele that produces this trait will not be under pressure from natural selection, and its frequency will remain unchangedQ. populationR. Members of 2 populations cannot interbreed and produce fertile offspringS. 1Random mating 2Very large population 3No movement into/out of population 4No mutations 5No natural selectionT. any change in a sequence of DNA |
