Which option best identifies the exact concept boundary for Variation and evolution, Selective breeding: students must explain that inbreeding can make some breeds prone to disease or inherited defects.

The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain that inbreeding can make some breeds prone to disease or inherited defects.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Selective breeding.

The correct option is Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain that inbreeding can make some breeds prone to disease or inherited defects.. Definition boundary: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Selective breeding because students must explain that inbreeding can make some breeds prone to disease or inherited defects. is correct because Mitosis produces identical cells; meiosis produces genetically different gametes. The learning objective says students must explain that inbreeding can make some breeds prone to disease or inherited defects, so the answer must stay inside Selective breeding. The alternative options are wrong because they either claiming mitosis produces gametes., forgetting chromosome number is maintained in mitosis but halved in meiosis., or drift away from meiosis questions must focus on gametes, halved chromosome number, sexual reproduction, or variation..
