Question
I am having trouble on #18. 17a. Suppose that your class repeated the simulation, but this time all the hunters were blind- folded so they could only find pom-poms by touch. For each habitat, predict the proportion of red and black pom-poms in the population at the end of the simulation. (Remember that at the beginning of the simulation half the pom-poms were red and half were black.) Black Forest: tan. (4 Red Grassland: ax.la 17b. Explain your reasoning.tat fo Survivin 17c. Based on this example, explain why evolution by natural selection can only occur if the variation in atrait results in differences in fitness. 18. Next, think about what would happen if your class repeated the simulation with hunters that could see, but pom-pom color was not heritable. In other words, the color of pom-pom offspring would not be related to the color of their parents. No matter how many pom-pom parents were red or black, half of the offspring would be red and half would be black. Based on this example, explain why evolution by natural selection can only occur if the variation in a trait is heritable. This simulation provides a useful basis for understanding many aspects of natural selection. However, it is important to note that, because a simulation necessarily simplifies the process that it mimics, there will be important differences between the simulation and biological process. For example: the actual In our simulation visual predation was the only factor that influenced reproduction of the pom-poms. In contrast, for real biological organisms, mortality is influenced by additional factors (e.g infection) and reproductive success is influenced by other factors in addition to survival. . mortality and .Also, in our simulation, each offspring had the exact same phenotype as its only parent, but, for most biological organisms, some of the offspring will have different characteristics than their parents. Because of these differences between our simulation and reality, natural selection would be slower in real biological populations. You will see an example of this in the next section.Explanation / Answer
18. natural selection is process of selecting best allel or allelic variation to fix in population which is best for their survival. if the variation in the trait is not heritable which means, the chance in allele or gene is occured for survival in environment, is not heritable the offsprings may not survive in population. variation in gene is arise due to mutations like deletion, duplication and SNPs. but if the change is not heritable in offspring, selection is not happened and ultimately over a time offspring will died. in our case if color of pom pom is not heritable than natural selection will not occure.
