Which method involves multiplying probabilities to solve independent assortment problems?

• A. Addition method
• B. Multiplication method
• C. Combination method
• D. Proportional method

Answer: (B)

The multiplication method is used for solving problems related to independent assortment in genetics because it applies the fundamental principle of probability that states the probability of two independent events both occurring is the product of their individual probabilities. In the context of genetics, when dealing with two or more traits that assort independently, the probability of each trait segregating into gametes can be calculated separately, and because these events do not influence each other, their probabilities can be multiplied together. For example, if the probability of a gamete containing one allele is 1/2 and another independent trait is also 1/2, the probability of obtaining a gamete with both traits is 1/2 * 1/2 = 1/4. This approach makes it straightforward to determine the likelihood of various genotypic combinations in offspring. Other methods mentioned, such as the addition method, are used for calculating the probabilities of mutually exclusive events, the combination method typically focuses on selecting subsets from a larger set, and the proportional method is less commonly referenced in basic genetics probability problems. Thus, the multiplication method is the correct choice for independent assortment problems as it directly follows the rules of probability for independent events.
