Problems10. If <strong>the</strong>re are 12 red beetles and 4 blue beetles in a population, what is <strong>the</strong> value <strong>of</strong> q? Remember thatblue is recessive.11. If <strong>the</strong> frequency <strong>of</strong> p in a population is 60%, what is <strong>the</strong> frequency <strong>of</strong> q?12. In a population <strong>of</strong> 1,000 O. glucosi beetles, 360 have red exoskeletons. The o<strong>the</strong>rs are blue. Howmany <strong>of</strong> <strong>the</strong> red beetles would you expect to be homozygous dominant?Questions13. If a mutation occurs, one consequence is that <strong>the</strong> allele frequencies in a population change. If in apopulation you are studying, <strong>the</strong> allele frequencies change, does this prove that a mutation hasoccurred? Explain why or why not.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________14. Use your class data from Chart 2 to determine <strong>the</strong> value <strong>of</strong> q 2 in <strong>the</strong> beetle population.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________15. Explain how natural selection and a color mutation associated with greater exoskeleton strengthinteract to result in evolutionary change in <strong>the</strong> beetle population.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________HHMI - Student Introduction to <strong>Survival</strong> <strong>of</strong> <strong>the</strong> Fittest—<strong>Battling</strong> <strong>Beetles</strong> Page 9 <strong>of</strong> 11
