Probability

Probability

Probability theory uses mathematics to measure the likelihood of something happening.  Probability theory may be applied in many areas, including genetics.

Materials for Probability

Articles/Research

Independent Assortment and Probability

Description: A well illustrated article explaining how to determine the likelihood that a squab (baby pigeon) will have a crest of feathers on its head.

Games

DNA Roulette

Description: This odds game makes learning about the probabilistic nature of genomics a blast. Unlike traditional roulette where the betting table and odds are always the same, DNA Roulettes odds are different for each disease or trait. Even within a disease, the odds are different depending on which of several possible genotypes is randomly selected by the game engine for that round.

Interactive Tutorials

Punnett Squares

Description: An interactive Punnett square activity
