  1. Hardy-Weinberg: Population Lab Data & Rubric Lab #8 (Chapter 23)

  2. Period 0-Data Collected (Part I) Allele Frequency (HW) % Tongue Rollers (p2 + 2pq) % Non-Rollers (q2) p q

  3. Period 1-Data Collected (Part I) Allele Frequency (HW) % Tongue Rollers (p2 + 2pq) % Non-Rollers (q2) p q

  4. Period 2-Data Collected (Part I) Allele Frequency (HW) % Tongue Rollers (p2 + 2pq) % Non-Rollers (q2) p q

  5. Part I: Answers • Class values will vary • North American Population: q2 = 0.45 q = 0.67 p = 0.33 p2 = 0.108 2pq = 0.44 ** Therefore 44% of the N. American Population are heterozygous

  6. Period 0-Data Collected (Part II) Class Totals for each Genotype Generation Offspring’s Genotype (AA, Aa, or aa) AA Aa aa

  7. Period 1-Data Collected (Part II) Class Totals for each Genotype Generation Offspring’s Genotype (AA, Aa, or aa) AA Aa aa

  8. Period 2-Data Collected (Part II) Class Totals for each Genotype Generation Offspring’s Genotype (AA, Aa, or aa) AA Aa aa

  9. Period 0-Data Collected (Part III) Class Totals for each Genotype Generation Offspring’s Genotype (AA or Aa) AA Aa

  10. Period 1-Data Collected (Part III) Class Totals for each Genotype Generation Offspring’s Genotype (AA or Aa) AA Aa

  11. Period 2-Data Collected (Part III) Class Totals for each Genotype Generation Offspring’s Genotype (AA or Aa) AA Aa

  12. Grading Rubric for Lab #8 • Pg. 69 Table 1 pt -Quest. #1 & 2 1 pt • Pg. 71 Table 1 pt • #1 Calc. AA, Aa, aa 1 pt • Initial frequencies: AA: 0.25, Aa: 0.50, aa: 0.25 1 pt • Recording the finding from #1 1 pt • Pg. 72 Calc Allele frequencies 2 pts • Pg. 73 Table & Calc. of Alleles 2 pts

  13. Topics for Discussion #1-3 • The p values tended to increase while the q values decreased. (2 pts)Pg. 73 total: 4 pts • The p values would continue to go up and the q values would continue to go down. (1 pt) • When comparing Part II (8B) with Part III (8C) there was a 14% frequency change from the initial frequency of 0.5 for p & q while in part III (8C) there was a 32% frequency change. A much greater change was observed when there was selection against the “a” allele. (2 pts) TOTAL for Pg. 74: (3 pts)

  14. Hardy Weinberg Problems #1-6 (pg. 96-97) • Homozygous dominant: 160 indiv. Heterozygous 480 indiv. 2pts 2. Homozygous dominant: 125 indiv. Heterozygous: 250 indiv. 2pts 3. Homozygous dominant: 90 indiv. Heterozygous 420 indiv. Homozygous recessive 490 indiv. 3pts 4. Homozygous dominant: 720 indiv. Heterozygous 960 indiv. Homozygous recessive 320 indiv. 3pts 5. Homozygous dominant: 640 indiv. Heterozygous 320 indiv. Homozygous recessive 40 indiv 3pts • Dominant allele (p) = 0.7 1 pt Showing work: 3pts TOTAL: 17 pts
