...frequency of the ester1 (blue) and ester4 (red) alleles in (a) 1986, (b) 1993 and (c) 1996. Activity 6 Describe the change in frequency with distance from the coast of both alleles over the three years. Answer In 1986, the frequency of the ester1 allele was nearly 0.6 at the coast and dropped to near zero at 50 km from the coast. Ester4 occurred at a low frequency at the coast and increased very slightly with distance from ......

...C. c.Zero gradient: graph A. d.Small positive gradient: graph B. e.Large positive gradient: graph D. Now let’s look at how the idea of gradient applies to curved graphs. For example, consider the graph of the equation y equals x squared , which is shown in Figure 6. [Described image] Figure 6 The graph of y equals x squared This graph has no single gradient value, since...
