Review for Exam 3 Four closely related topics this time: Meiosis and gamete formation; patterns of genetic inheritance (Mendelism, linkage); transcription & translation (the “central dogma” of molecular genetics); and the control of gene expression and how it relates to development and evolution of body plans. A more detailed (though perhaps not comprehensive) list: What is the “cost” of sex in terms of how many of your chromosomes are passed on to the next generation? Costs to asexual reproduction: Muller’s ratchet (accumulation of errors), Red Queen (evolutionary arms race) Which kind of reproduction can produce more offspring, more quickly? Why is this so? The advantages of sexual reproduction—how are variable offspring an advantage? How does the Red Queen hypothesis relate to evolution of drug or pesticide resistance? How does meiosis generate genetic variability? Why does crossing over happen in meiosis but not mitosis? Which is more like mitosis: meiosis I or meisis II? Mitosis vs Meiosis: ploidy of parent and daughter cells Can “selfing” generate variable offspring? Transmission (Mendelian) Genetics
