1. What prediction does the neutral theory make that isnot true and what modification was made to itsassumptions to produce a new theory created by Ohta that better fitthe data?

A) genetic change should be constant/most mutations are undervery weak selection

B) evolutionary rate should be a function of mutation rate pergeneration/most mutations are under very weak selection

C) evolutionary rate should be a function of mutation rate pergeneration/drift is not acting

D) evolutionary rate should be a function of mutation rate pergeneration/most mutations are under very strong selection

E) genetic change should be constant/most mutations are undervery strong selection

2. In a hypothetical situation a flu pandemic is spreadingacross the world (in humans). The virus is sequenced and is foundto be an H1N3 virus. A phylogeny of viruses find that this virus ismost closely related H1N1 viruses but that the gene for N3 is mostclosely related to the 'N' gene in pigs. What is the most likelyevolutionary scenario for this situation?

A) The pig virus has switched hosts to attack humans

B) Human and pig viruses recombined in a host cell

C) Human and pig viruses mated and recombined

D) The viral gene for 'N' underwent extensive parallelevolution

E) N1 mutated to N3
