Mendel’s Two Laws  Law of Segregation: Alleles for a trait segregate during gamete formation (Meiosis)  Law of independent Assortment: Genes for different traits assort independently of each other during gamete formation (meiosis)

Class work: Genetic Disorders Test: Friday, Nov. 22 nd

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)

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?
