Rules

  • Each team has 15 seconds to write an answer using the resources provided (e.g., dry-erase board, Google doc, scratch paper, etc.).
  • Students can collaborate within their assigned teams but cannot get outside help.
    • Teams automatically lose points for a round if they get help from outside their team (e.g., from another team or using notes).
  • Each team either gains or loses points on each turn.

10 of 34

Mitosis

  • Prior to cell division, a cell must _____ its DNA.

11 of 34

Mitosis

  • This protein helps to wrap DNA into tight coils to form a chromosome.
  • Histones

12 of 34

Mitosis

  • This protein helps to align and evenly divide chromosomes so that each copy of the cell receives an equal amount of DNA.

15 of 34

Meiosis

  • These are examples of gametes.
  • Sperm and/or egg cells

16 of 34

Meiosis

  • Sperm cells are ____, meaning they have only one copy of each gene/chromosome.
  • Haploid

17 of 34

Meiosis

  • Cells that have two copies of each chromosome are known as...
  • Diploid

​

18 of 34

Meiosis

  • During this process, chromosomes exchange similar segments to increase genetic diversity.
  • Crossing Over�

19 of 34

Predicting Traits

  • If an organism possesses this kind of gene, it is always expressed as a trait.
  • Dominant.

20 of 34

Predicting Traits

  • If an organism possesses this kind of gene, it is only expressed as a trait under certain conditions.

22 of 34

Predicting Traits

  • Person A is homozygous dominant for eye color and has brown eyes. Person B is homozygous recessive and has blue eyes. What are the odds they will have a child with blue eyes?
  • 0% (Person A = EE; Person B = ee; all offspring will be Ee, or brown eyed).

23 of 34
