Probability laws govern Mendelian inheritance * Mendel?s laws of segregation and independent assortment reflect the rules of probability * When tossing a coin, the outcome of one toss has no impact on the outcome of the next toss * In the same way, the alleles of one gene segregate into gametes independently of another gene?s alleles The Multiplication and Addition Rules Applied to Monohybrid Crosses Figure 14.9 * The multiplication rule states that the probability that 2 or more independent events will occur together is the product of their individual probabilities * Probability in an F1 monohybrid cross can be determined using the multiplication rule
