Assume that you conduct a testcross (aabb x aabb) and find that the recombination frequency between a and b is 35% which would correspond to a map distance of 35 mu. why is this value likely an underestimation of the true map distance between the two genes? how might you determine a more accurate map distance? (you don't have to find a particular distance that would be more accurate, just describe how you would go about doing it? )

Extensive and unusual cold snaps have occurred here recently. is this evidence that global warming is lessening or not occurring? no—although the long-term trend is for warming, short-term weather patterns can still be variable. no—melting of glaciers and ice caps is making the oceans cooler, which can cause cold snaps. yes-- if global warming really were occurring, cold snaps wouldn’t happen. yes—due to global warming, weather patterns should be become less—not more—variable.
