Answer:
Mutations can create entirely new alleles in a population which changes the allele frequencies of a gene pool.
2. High birth rate, zero death rate, high immigration, zero emigration
This is because birth rate and immigration increase population size, and death rate and emigration decrease population size, so maximizing the former and minimizing the latter are ideal
