LEGO® Animations of Cell Division! The LEGO® Chromosome Set can be used to illustrate the two kinds of cell division: mitosis and meiosis. The key concept here is that mitosis produces identical cells while meiosis does not. The LEGO® fish in the set has three pairs of chromosomes with genes for the colors of the fish's tail, fin and spots.

LEGO fish! The chromosomes show the genes for the body colors.
The LEGO® Fish has three pairs of chromosomes: Chromosome 1 has the gene for tail color: green or white. Chromosome 2 has the gene for fin color: red or brown Chromosome 3 has the gene for spot color: blue or red
The gene color underlined above is dominant. (The word dominant means that in cases where a fish has two different color genes on a pair of chromosomes, the underlined gene color will be the winner.)
Teaching Tips 1) Show the LEGO™ Mitosis or Meiosis Animation before you do the LEGO™ Chromosomes activity.This preview will help everyone understand what they are about to do. It's cool.
2) Use the animationto lead everyone through the activity (Use the pause control). Advice: In the MEIOSIS simulation you do not need to use the green microtubules as shown. It adds too much complexity. Use them only in mitosis.
