Guided Reading Chapter 9 (Read pages 153-169)1.) Define heredity and describe how it relates to the term “genetics.”2.) What is self-fertilization and how does this form of fertilization differ from cross-fertilization?3.) Why do you think that it was important that Mendel understood and could control for how plants are fertilized? 4.) What is a true breeding plant? 5.) What is a hybrid?6.) Rank the following generations from youngest to oldest – F2, P, F1.7.) A researcher is studying the inheritance of a single gene so she performs a monohybrid cross with two heterozygous individuals. What ratio will she observe in the F2 generation?8.) Define the following a. Homozygous:b. Heterozygous:c. Allele:d. Recessive:e. Dominant:f. Phenotype:g. Genotype:h. Punnet square:9.) A lot of what we know about the field of genetics has emerged from work on fruit flies! In flies, the allele for red eye color is dominant over the allele for white eye color. If you came across a red fly and wondered whether it was a homozygote or a heterozygote, how could you determine its genotype?10.)Describe how the rule of multiplication can be applied to a monohybrid cross.11.)What does the term “wild type” mean?12.)Many genetic disorders are caused by mutations in a single gene. Determine whether or not you think a phenotypically normal parent can have offspring with a recessive disorder. A dominant disorder? Why or why not?13.)Describe at least three different ways that physicians can test a fetus for a genetic disorder.14.)Identify a risk associated with amniocentesis and/or CVS.15.)How does incomplete dominance differ from the blending hypothesis that was proposed and later disputed early in the 19th century?16.)Can more than one allele exist for a single trait?17.)Individuals with the AB blood type express both the A and the B allele in theirred blood cells. Individuals with blood type O do not express either the A or the B allele. How do the red blood cells differ between individuals that are IAIB and individuals that are ii? a. Explain how these differences affect who different individuals can donate blood to.18.) In Mendels work, a single trait was determined by a single gene. Can a single gene affect many different phenotypes? a. Can multiple genes affect a single
