Question

On the right is a figure showing the reconstructed route of colonization of a rodent species found on the continent and four offshore islands, A, B, C, and D. Since the ocean currents around these islands are extremely strong, you suspect that these colonization events are rare, likely have happened only once. To estimate the overall genetic diversity of each population, you surveyed alleles frequencies of several neutral loci. Which of the following statements is correct?

 

   

The genetic diversity would be the highest on island D because all migrations ended up on the island.

   

If the level of genetic diversity is plotted against the distance from continent, we would expect to observe a steady increase of genetic diversity as the distance becoming farther away from the continent.

   

The genetic diversity on island A would be lower than that of the continent because there is selection on the island removing deleterious alleles.

   

This is an example of founder effect.

   

All of the above
