Meiosis and genetic diversity: grass skirts

13 quick questions on AP Biology topics 5.1 Meiosis and 5.2 Meiosis and Genetic Diversity, each answered in a word or two. Print a sheet for each team, a key for the checker and a tick sheet, then tape the sheets to the board and race.

How it runs

  1. SnipA runner cuts one strip off the bottom of their team’s sheet.
  2. Answer as a pairBack at the table, they write the answer on the strip. No books.
  3. Get it checkedThe checker reads it against the key: you, or a student holding it.
  4. Back for the nextA tick earns the next strip. Wrong? Back to the table to try again.

The questions on this sheet

The checker’s key, with every answer, prints with the sheets.
  1. Division making four haploid gametes
  2. Having one set of chromosomes (n)
  3. Having two sets of chromosomes (2n)
  4. Sex cell such as a sperm or egg
  5. Fusion of two gametes to restore 2n
  6. Same-size pair carrying the same gene loci
  7. Non-sister chromatids exchange segments
  8. Joined copies that part in meiosis II
  9. Stage when crossing over happens
  10. Stage when homologous pairs separate
  11. Close pairing of homologs early in meiosis
  12. Random orientation of pairs at metaphase I
  13. Visible X-shaped contact between homologs
