MRSA) True or False: Bacteria can exchange genes with species. - Answer- True Homology - Answer- Similarity due to common ancestry - Similar structure, different function Vestigial structure - Answer- Remnants of a structure that once served a function of an organism's ancestor True or False: All life shares the same genetic code - Answer- True Convergent Evolution - Answer- Independent evolution of similar features in different lineages -Separate species but adapted to similar environments in similar ways Analogous structures - Answer- Similar function but different structure -No common ancestry A unifying theory does not become accepted unless... - Answer- Lots of evidence and data and tests Biogeography - Answer- -Continental drift -Pangea -Endemic Species Endemic Species - Answer- Species found nowhere else in the world, isolated in one place 4 categories of evidence supporting Darwin's theory - Answer- -Fossil Record -Biogeography -Homology -Direct Observation Thomas Malthus - Answer- Species produce more than the environment can produce Direct Observation - Answer- Directly observing/evaluating data based on environment Ex: Darwin's Finches (beak length) Transitional Fossils - Answer- Modern animals are very different from fossilized animals: proves evolution Developmental homologies - Answer- Structures that exist during development but go away Cellular/Molecular Homologies - Answer- Similarity of cell structures, proteins, DNA 5 requirements for Hardy-Weinberg Equilibrium - Answer- -Large population -No gene flow -No mutations -No natural selection -Random mating In wild melon plants, the melon flesh color is determined by incomplete dominance at a single locus. (FF-red flesh, Ff= orange flesh, ff- yellow flesh). In a population in a HW equilibrium, 16% produce melons with yellow flesh. What proportion of
