Description
In the MathBench module on probability, the Laws of Probability were discussed that can be applied to, well, just about anything - rolling dice or determining the probability of survival, or playing the stock market, or genetics, to name a few. In this module, we're going to talk about another approach to probability, which is much more specific to genetics, called Punnett Squares. Punnett Squares were invented by one Reginald Punnett, a British geneticist who also studied ribbon worms and played cricket with G. H. Hardy of Hardy-Weinberg fame, one of the true big cheeses in the genetics world.
In this module, you'll see how Punnett Squares are really just a graphical way of reproducing the basic rules of probability.
You'll also see how to predict the phenotypic outcome from a multi-loci genotypic cross in other words, how to predict what the kids will look like.
