The sailfin molly, Poecilia latipinna, is an interesting freshwater fish possessing internal fertilization. In this species, males either court females or attempt forced copulations without courting. Larger males court more frequently than smaller males whereas the latter attempt more forced copulations. Variation in male size appears to be strongly influenced by alleles at a single genetic locus on the Y chromosome. Describe simple genetic crosses and an experiment in which you could determine whether the two male behaviors represent either...

4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...
