For this question you will practice the skill of paraphrasing again. Remember that paraphrasing means completely rephrasing and stating the main points of the original information in your own words.    To paraphrase, you should form completely new sentences. Only switching the front and back halves of a sentence or replacing the original words with synonyms does not constitute appropriate paraphrasing (though these strategies can be used in successful paraphrasing along with other strategies).   Look back at Lab 1: Life and Scientific Inquiry for good and bad examples of paraphrasing (pre-lab content) and an example paraphrasing procedure (lab activity). For more tips for paraphrasing, check out this linkLinks to an external site..     Choose one of the following passages describing a mechanism of evolution (from the pre-lab) to paraphrase. Your passage should cover the same basic information as the original but in your own words.   Passage Option 1: A mutation is a change in the DNA sequence of a gene, which can result in a new gene variant or allele. This change usually occurs as a copying "error" when the DNA sequence is being replicated. Mutation is the original source of all new alleles. Passage Option 2: Gene flow occurs when alleles enter or leave the population due to individuals immigrating or emigrating. Individuals entering or leaving the population can either change the frequencies of the alleles that are already in the population, or they can introduce new alleles.
