The idea of mutation was brought forth by:  

1.  Hardy Weinberg, who worked on allele frequencies in a population.
2.  Charles Darwin, who observed a wide variety of organisms during the sea voyage.
3.  Hugo do Vries, who worked on evening primrose.
4.  Gregor Mendel, who worked on PisumSativum.

A population geneticist finds that a new allele in a population has suddenly increased in frequency. Most likely this allele is:
1. mutating rapidly
2. flowing with emigrants
3. strongly selected for
4. a product of assortative mating

An island population faced a natural calamity and the population crashed to only 30 organisms. After some time the number of organisms grew to 5000 but still the threat of extinction is large. This is most likely due to:
