DEFINITION
Autosomal Recessive Disorder
A type of genetic disorder in which two copies of a mutant allele (one from each parent) are required for the trait to be expressed. In the book, albinism is used as a classic example of this disorder.
Explain how auxotrophic bacteria are isolated.
What is the difference between complete medium and minimal medium? How are complete media and minimal media to which has been added one or more nutrients (supplemental media) used to isolate auxotrophic mutants of bacteria?
Briefly explain the differences between $\mathrm{F}^{+}, \mathrm{F}^{-}, \mathrm{Hfr},$ and $\overline{\mathrm{F}^{\prime}}$ cells.
What types of matings are possible between $\mathrm{F}^{+}, \mathrm{F}^{-}, \mathrm{Hfr},$ and $\mathrm{F}^{\prime}$ cells? What outcomes do these matings produce? What is the role of F factor in conjugation?
Explain how interrupted conjugation, transformation, and transduction can be used to map bacterial genes. How are these methods similar and how are they different?
