New combinations of DNA and genes can come from different sources in the genetic material that is passed from to offspring. Sources of genetic material can come from in meiosis I, errors during, in meiosis, and from environmental factors. When these new combinations are passed on to, this increases - potentially, the species. Remember, for a mutation to be passed on through sexual reproduction (meiosis), the change to the MUST be present in the. Word Bank:
