3 The frequency of a particular recessive allele in a population of chipmunks is .3 The frequency of the dominant allele in this same population is: .3 .6 .7 1 10 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

4 You have determined the frequency of the dominant allele in a population. Over the next two generations, the frequency of this allele does not change. Which factors below must be true in order to maintain this equilibrium: Random mating Large population size No natural selection No gene flow No mutations 10 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
