Please I need your help to answer these questions. Thanks in advance, PowerPoint Guide 8.3-8.4 Extension of Mendelian Genetics and Sex and Inheritance 1. Explain how polygenic and pleiotropic traits differ. 2. How is incomplete dominance different than normal Mendelian genetics? Give an example. 3. How is codominance different than incomplete dominance? Give an example. 4. Describe the inheritance of the multiple-allelic ABO blood system. 5. Which blood type is considered the universal donor? Why does that make sense biologically? 6. Which blood type is considered the universal acceptor? Why does that make sense biologically? 7. Do all animals exhibit the same type of X and Y sex chromosomes as humans? Give an example. 8. Do human males or females determine the gender of their offspring? Explain. 9. Why is it rare for human females to have colorblindness? 10. Explain how scientists use pedigrees. (by the way, autosomal just means the normal 22 chromosomes, not the sex chromosomes).
