n an experimental science, such as genetics, scientists make decisions about hypotheses on the basis of data gathered during experiments. Geneticists must therefore have an understanding of probability theory and statistical tests of hypotheses. Probability theory allows geneticists to construct accurate predictions of what to expect from an experiment. Statistical testing of hypotheses, particularly with the chisquare test, allows geneticists to have con dence in their interpretations of experimental data. probability that the next child born will have phenylketonuria is 1/10,000. The odds based on the geometry of an event are, for example, like the familiar toss of dice. A die (singular of dice) has six faces. When that die is tossed, there is no reason one face should land up more often than any other. Thus, the probability of any one of the faces being up (e.g., a four) is onesixth: P a/n 1/6 Similarly, the probability of drawing the seven of clubs from a deck of cards is P 1/52 PROBABILITY
Part of Gregor Mendel s success was due to his ability to work with simple mathematics. He was capable of turning numbers into ratios and deducing the mechanisms of inheritance from them. Taking numbers that did not exactly t a ratio and rounding them off to t lay at the heart of Mendel s deductive powers. The underlying rules that make the act of rounding to a ratio reasonable are the rules of probability. In the scienti c method, scientists make predictions, perform experiments, and gather data that they then compare with their original predictions (see chapter 1). However, even if the bases for the predictions are correct, the data almost never exactly t the predicted outcome. The problem is that we live in a world permeated by random, or stochastic, events. A bright new penny when ipped in the air twice in a row will not always give one head and one tail. In fact, that penny, if ipped one hundred times, could conceivably give one hundred heads. In a stochastic world, we can guess how often a coin should land heads up, but we cannot know for certain what the next toss will bring. We can guess how often a pea should be yellow from a given cross, but we cannot know with certainty what the next pod will contain. Thus, we need probability theory to tell us what to expect from data. This chapter closes with some thoughts on statistics, a branch of mathematics that helps us with criteria for supporting or rejecting our hypotheses. The probability of drawing a spade from a deck of cards is P 13/52 1/4 The probability (assuming a 1:1 sex ratio, though the actual ratio is about 1.06 males per female born in the United States) of having a daughter in any given pregnancy is P 1/2 And the probability that an offspring from a selffertilized dihybrid will show the dominant phenotype is P 9/16 From the probability formula, we can say that an event with certainty has a probability of one, and an event that is an impossibility has a probability of zero. If an event has the probability of P, all the other alternatives combined will have a probability of Q 1 P; thus P Q 1. That is, the probability of the completely dominant phenotype in the F2 of a selfed dihybrid is 9/16. The probability of any other phenotype is 7/16, and when the two are added together, they equal 16/16, or 1.
