Activity: Factors involved in Natural Selection / Interpreting X-Y graphs The boldness of bass A recent study of largemouth bass, a type of freshwater fish, showed that individual fish have distinct personality types. The researchers looked at a fish's willingness to explore a new environment, which they called boldness. A more bold fish is one that will readily explore when placed in a new setting. Their study considers if boldness may be an adaptive trait, that is, subject to natural selection. The researchers therefore looked at the correlation between parent and offspring boldness scores, as shown in the figure. A. What pattern is illustrated by this figure? What factor(s) necessary for natural selection are shown in this graph? The association between the boldness scores OF Parents & Children is depicted in the image. Offspring boldness score I+ demonstrates the heredity Of audacity, an element required For natural selection 0.5- 0.0- -0.5- -1.0- 0.5 1.0 Parent boldness score Figure 1: Relationship between parent and offspring boldness score B. What other crucial piece of information do you need to have to know that fish boldness could be subject to natural selection? Why? variation, Heritability, & Differential Fitness. You need to know if there is a heritable genetic basis for boldness C. What data would you collect to gain the information needed in question 2B above? Draw a plot of a pattern you might expect to see in these data if boldness is indeed subject to natural selection. Label your axes. Briefly explain the pattern you've drawn and predict what effect it would have on the frequency of more bold or less bold fish in a bass population over time. Data plot (label axes) Describe pattern and predict effect on population
