11:57LTE6 of 13Question 6My ResponseThe three-spined stickleback (Gasterosteus aculeatus) is aspecies of fish that has both marine and freshwaterpopulations. There are genetic differences between thepopulations in the different environments. The graph shows thefrequency of a certain allele in freshwater and marinepopulations of stickleback fish.FREQUENCY OF ALLELEIN TWO POPULATIONS1.0-0.9-0.8-0.70.60.50.40.30.20.10-MarineFreshwaterLocation of Stickleback PopulationIn 1978, scientists studied how the fitness of marinesticklebacks would be affected if they were introduced into afreshwater environment. They collected 90 male and 90 femalesticklebacks from a marine population and 10 male and 10female sticklebacks from a freshwater population. The 200sticklebacks were introduced into a freshwater environmethat had no stickleback fish previously.SubmitAAA apclassroom.collegeboard.orgFrequency of Allele Question 6My ResponseRecently a scientist decided to repeat this study, but relocateda population of sticklebacks from a freshwater environmentinto a marine environment.
