Which option correctly contrasts the named ideas for Variation and evolution, Variation: students must describe that most mutations have no effect on phenotype, some influence phenotype, and very few determine phenotype.

The correct option is Correct contrast: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Variation because students must describe that most mutations have no effect on phenotype, some influence phenotype, and very few determine phenotype.. It is the only option that keeps Mitosis vs meiosis separate and answers the approved learning objective in Variation.

The correct option is Correct contrast: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Variation because students must describe that most mutations have no effect on phenotype, some influence phenotype, and very few determine phenotype.. Correct contrast: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Variation because students must describe that most mutations have no effect on phenotype, some influence phenotype, and very few determine phenotype. is correct because Mitosis produces identical cells; meiosis produces genetically different gametes. The learning objective says students must describe that most mutations have no effect on phenotype, some influence phenotype, and very few determine phenotype, so the answer must stay inside Variation. 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..
