Evolution as genetic change in populations1.If a trait made an organism less likely to survive and reproduce, what would happen to the allele for that trait?2.If a trait had no effect on an organism’s fitness, what would likely happen to the allele forthat trait? Use the table showing the evolution of a population of mice to answer Questions 3–5.Initial PopulationGeneration 10Generation 20Generation 3090%80%70%40%10%20%30%60%3.Is the trait for fur color a single-gene trait or a polygenic trait? Explain your answer.4.Describe how the relative frequency of fur color alleles is changing in this population andpropose one explanation for this change.5.Suppose a mutation causes a white fur phenotype to emerge in the population. What
might happen to the mouse population after 40 generations?6.What effect does stabilizing selection have on variation in a population?7.Natural selection works on an organism’s rather than its 8.A(n) consists of all the genes, including the alleles for each gene, that .
