2.21.14 Today: Lighter side of genetics: positive stories Applied Genetics: Who’s your daddy investigation Genetics Position paper (mini-Tia)

Applied Genetics: Copy these alleles down • Allele key: • Widow’s peak: • W=Widow’s peak • w=no widow’s peak • Attached/free earlobes: • E=Free earlobes • e=attached earlobes • Blood types • IA=type A • IB=type B • i=type O
Who’s the daddy? There has been a polar vortex that made snowmageddon look like a flurry. The University of Chicago’s pediatric ward has a new nurse (Nurse Jackie) who, in her hurry to evacuate the hospital, forgot to put ID bracelets on the newborn babies! You need to use your knowledge of genetics and heredity to deliver the babies to their correct parents.
What do the babies look like? • Baby #1 • No Widow’s peak • Attached Earlobes • Blood type: A • Baby #2 • Widow’s Peak • Attached Earlobes • Blood type: O • Baby #3 • Widow’s Peak • Free Earlobes • Blood type: B For each phenotype, we’ll need to establish the POTENTIAL genotypes
Why can’t we just do a genetic test?!? There’s no power There’s no time! That would be missing the whole point of applying our knowledge of genetics!!!
1st set of parents • Mr. Al Leel • Widow’s Peak • Attached Earlobe • Blood Type: B • Mrs. Allie Leel • No Widow’s Peak • Free Earlobe • Blood type: AB
2nd set of parents • Mr. Hap Lloyd • Widow’s Peak • Attached Earlobe • Blood Type: A • Mrs. Diana ‘Dip’ Lloyd • No Widow’s Peak • Attached Earlobe • Blood type: AB
3rd set of parents • Eugene Poole • No Widow’s Peak • Free Earlobes • Blood Type: B • Alice Poole • Widow’s Peak • Free Earlobes • Blood type: A
What terms should we know at this point? • Alleles • DNA base • Chromosomes • Chromatids • Co-dominance • Crossing over • DNA • Dominant • Genes • Gene expression • Genetic variation • Genetics • Genome • Genotype • Heredity • Heterozygous • Homozygous • Hybrid • Meiosis • Mitosis • Mutations • Phenotype • Protein • Recessive • RNA • Trait
What’s our net unit about? • Genetic MANIPULATION
Genetic Testing position paper • Due typed by Wednesday (Our next unit is also about genetics) • Attached: Outline (also typed) including • Pg 1: Thesis/position • Pg 2: Support 1 • Pg 3: Support 2 • Pg 4: Support 3 • Pg 5: Counterargument • Pg 6: Counterargument • Pg 7: Conclusion (referring back to both arguments and counterarguments)
Example of outline • Intro Position: • Support 1: • Support 2: • Support 3: • Counterargument: • Counterargument: • Conclusion:
Example of outline • Intro Position: I am for genetic testing • Support 1: Source A, “Provides a wealth of information” • Support 2: Source A, “Ability to plan for unavoidable issues” • Support 3: Source A, “Genetic disease as social burden.” • Counterargument: Source C Positive perspectives of DS parents • Counterargument: Source C ~90% of women given a DS diagnosis choose abortion • Conclusion: I am for genetic testing because it provides information, the ability to plan for unavoidable issues, and the choice to avoid a social burden. One could argue against this positive by sharing the positive perspectives from parents of DS children, and pointing out that genetic testing often leads to abortion.
