The image represents a genetic procedure. Which statement best describes the outcome of the procedure?

• Bacterial cells will destroy defective human genetic material

• The inserted human DNA will change harmful bacteria to harmless ones

• Bacterial cells form a multicellular embryo

• The inserted human DNA may direct the synthesis of human proteins

Which statement about the evolution of species A, B, C, D and E is supported by the diagram?

• Species B and C can be found in today's environment

• Species A and D evolved from E

• Species A and C can interbreed

• Species A, B and E all evolved from a common ancestor and are successful today

Genetic drift is change in the allele frequency of a population due to...

• random chance
• natural selection
• non-random mating (sexual selection)
• artificial selection

This mechanism of evolution occurs when populations migrate.

• Extinction
• Gene flow
• Genetic drift
• Natural Selection

Which of the following cannot introduce new alleles into a population's gene pool?

• Mutataion
• Natural selection
• Gene Flow
• All of the above introduce new alleles into the population
