A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

• Genetic Drift- founder effect

• Natural Selection

• Non-random mating

• Mutation

Which of the following statements is supported by the graph below?

• The population is in Hardy-Weinberg equilibrium, as the sum of the frequency of the dominant allele and the recessive allele is always equal to 1
• The percentage of individuals homozygous recessive for this particular trait is increasing over time
• Selection has caused frequencies to change over time because individuals with a dominant allele survive at higher rates than individuals with recessive alleles
• Individuals who are homozygous recessive for this particular trait have migrated into the population, causing the frequency to approach 1
