2 Biology Reference Tables are New There is a push to make AP biology more quantitative, mathematicalThere are aspects of these tables that have not appeared in old curricula; little guidance for teachers on how to use, no questionsStudents did poorly on mathematical questions on last year’s test
3 Statistical Analysis and Probability The AP Bio curriculium focuses on statistics based on counts, not continuous variables
4 Using You Reference Tables… What is the mode of the following data set?6, 8, 1, 6, 5, 6, 8, 3, 4, 2What is the median of the following data?2, 5, 7, 2, 4, 6, 9, 11, 3What is the range of these observations of plant mass?0.20, 0.35, 0.41, 0.22, 0.32, 0.14
10 Remember Chi-Square tests only work with counts This test was developed for Mendelian genetics; a part 2 question is likely this yearLast year, animal behavior question (choice chamber)
11 2003 Exam, Question 1In fruit flies, the phenotype for eye color is determined by a certain locus, E indicates the dominant allele and e represents the recessive allele. The cross between a male wild-type fruit fly and a female white-eyed fruit fly produced the following offspring:Wild-Type MaleWild-Type FemaleWhite-eyed MaleWhite-Eyed FemaleBrown-Eyed FemaleF145551
12 The wild-type and white eyed individuals from the F1 generation were then crossed to produce the following offspring.Wild-Type MaleWild-Type FemaleWhite-eyed MaleWhite-Eyed FemaleBrown-Eyed FemaleF223312224Determine the genotypes of the original parents (P generation) and explain your reasoning. You may use Punnett squares to enhance your description, but the results from the Punnett squares must be discussed in your answer.

14 Use a Chi-squared test on the F2 data to analyze your prediction of the parental genotypes. Show all of your work and explain the importance of your final answer.Wild-Type MaleWild-Type FemaleWhite-eyed MaleWhite-Eyed FemaleBrown-Eyed FemaleF223312224
15 The brown-eyed female in the F1 generation resulted from a mutational change. Explain what a mutation is, and discuss two types of mutations that might have produced the brown-eyed female in the F1 generation.
17 In fruit flies (Drosophila melanogaster), straight wing shape is dominant to curly wing shape. A particular population of fruit flies is in Hardy-Weinberg equilibrium with respect to the alleles for wing shape.The Hardy-Weinberg equation, given below, is useful in understanding population genetics:p2 + 2pq + q2 = 1Explain what the terms ( p2, 2pq, and q2 ) represent in the population of fruit flies.Describe one condition that is necessary for the population to be in equilibrium.
