Questions and Answers

What is the main reason why speciation is usually a slow process?

  • Plants have diploid cells
  • Gametes are haploid
  • Mutation rate is very high
  • Allele changes accumulate slowly (correct)

    • What is abrupt speciation in plants characterized by?

  • Involving haploid gametes
  • Resulting in diploid cells
  • Slow process over many generations
  • Happening within a single generation (correct)

    • Why can abrupt speciation occur in some plant species?

  • Because of high mutation rates
  • Plant cells can remain viable even when polyploid (correct)
  • Gametes always stay haploid
  • Due to diploid cells in plants
