Those better at sprinting tend to have… which produces… I (would/would not) have my child tested for the speed gene because… I (would/would not) want to know if I have the ApoE4 gene because… After reading this article, I believe elite athletes are a result of… The most interesting thing I learned from this article was… Friday, Nov. 15th Objective: Students will apply their advanced knowledge of genetics to solving pedigrees and determining relationships among offspring. Discussion: Pedigrees Worksheet Pedigrees Class work: Pedigrees Test: Friday, Nov. 22nd Monday, Nov. 18th Objective: Students will understand some common genetic disorders. Turn in Pedigree Go Over Genetics Worksheet. Genetic Disorders Gallery walk Given your topic construct a genetics problems that another group can answer. Class work: Genetic Disorders Test: Friday, Nov. 22nd Sickle Cell Anemia Single Recessive Gene Homozygous Recessive – Cells Sickle Causes difficulty in blood transmission of blood Heterozygous – resistant to Malaria Tay-Sachs Recessively Inherited Gene is on Chromosome 15 Blocks production of an enzyme that breaks down fat in brain Fat accumulates in the brain’s nerve cells Child – Dies normally before 5 years of age Cystic Fibrosis Recessive Disorder 4% of European descent are carriers Homozygous Recessive Defective protein to transport chloride Chloride Causes mucus to build up – multiple problems from breathing too digestion Huntington’s Disease Dominantly inherited Neurodegenerative disorder Late onset (35-55yrs) Breast Cancer Gene BRCA – 1 and BRCA – Tumor Suppressing genes Mutations – linked to increase in Ovarian Cancer and Breast Cancer Normal Rates 1.5% With Mutation 15 – 40% Questions: You are newly pregnant. You and your husband go to the doctor and test the fetus for various genetic disorders. The test comes back positive for Tay-Sachs, what do you do? You find out that your father has Huntington’s disease. Do you get tested for the gene? You are 30 years old and a friend talks to you about getting tested for the BRCA gene mutation. Do you get tested? Tuesday, Nov. 19th Objective: Students will understand how ther Hardy Weinberg Equation can predict allele frequencies and future generations Discussion: Hardy Weinberg Worksheet. Test: Friday, Nov. 22nd Wednesday, Nov. 20th Objective: Students will understand the Hardy Weinberg equation. Worksheet.
