Which option gives the correct cause-and-effect relationship for Variation and evolution, Cloning (biology only): students must describe cuttings as an older simple method for producing identical new plants from a parent plant.

The correct option is Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Cloning (biology only) because students must describe cuttings as an older simple method for producing identical new plants from a parent plant.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Cloning (biology only).

The correct option is Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Cloning (biology only) because students must describe cuttings as an older simple method for producing identical new plants from a parent plant.. Correct cause and effect: Mitosis maintains chromosome number; meiosis halves chromosome number. This matches Cloning (biology only) because students must describe cuttings as an older simple method for producing identical new plants from a parent plant. is correct because Mitosis maintains chromosome number; meiosis halves chromosome number. The learning objective says students must describe cuttings as an older simple method for producing identical new plants from a parent plant, so the answer must stay inside Cloning (biology only). The alternative options are wrong because they either claiming meiosis is used for body growth., claiming mitosis produces gametes., or drift away from mitosis questions must focus on identical cells, growth, repair, asexual reproduction, or maintained chromosome number..
