Lecture 16 1. What factors seem to be altering Mendelian ratios ? 2. Explain the pedigree of the Simmons Family . What symptoms did Anthony have?What symptoms did Tim have? What symptoms did Charlie have? What type of disorder is Tourette Syndrome ? Why is it difficult to diagnose? Did Eva have Tourette Syndrome? 3. What is a lethal allele ? What happens to the progeny class that expresses a homozygous recessive trait ? Discuss the mating of Mexican Hairless dogs. Which progeny class is eliminated early due to a lethal allele? What are the genotypes of the survivors? 4. Using Topic 3 Animation 1 , discuss the condition of the Creeper Chickens . What genotype is normal? What genotype presents the Creeper condition? What genotype is removed from the progeny class due to a lethal allele combination? 5. Define a multiple allele trait ? How many alleles can one person have for a trait? How does this type of trait affect Mendelian ratios? Give an example of a multiple allele trait and explain as much as you can about it? How many alleles are possible? What allele combinations are there ? How many different phenotypes exist? Discuss how the different phenotypes can be beneficial or harmful. 6. What is an antigen ? What is an antibody ? Why is this important in testing for blood type? On the membrane of the blood cell is the H substance that attaches to the specific antigen for blood type. Explain the different membrane antigens for each blood type. 7. What is an agglutination reaction ? How is it used to test for blood type?

Discuss which blood types seem to be compatible and which seem to be incompatible. What blood type is the universal doner ? What blood type is the universal recipient ? 9. Using the Information in Topic 4 Figure 6 , complete the punnet square and determine what blood type the parents have. 10. Discuss incomplete dominance .
