MIT Department of Biology 7.014 Introductory Biology, Spring 2005 Recitation Section 16 April 6-7, 2005 Recombination and Pedigrees A. Chromosomes and Recombination 1. What is the physical basis of the genetic phenomenon of gene recombination? 2. Why is the recombination frequency between two genes correlated with the physical distance between the two genes? 3. Recombination can occur anywhere along the length of the chromosome. However, we have been relying on the fact that genes are inherited as discreet units. How do we reconcile these two things? (Hint: think about what usually is the difference between two alleles of the same gene.) 4. Why is the highest possible recombination frequency 50%? B. Pedigrees In 1901 a physician in London named Archibald Garrod had some new patients with an unusual condition: when their urine came into contact with air it turned black. 1. What is the wild-type phenotype? 2. What is the assay? 3. Who are the mutants?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
