Humboldt penguins spend a majority of their time in coastal waters. The amount of time the spend in water is associated with breeding status.

In a randomly mating (or panmictic) population, allele frequencies are expected to be roughly similar between groups. However, mating tends to be non … See more The basic cause of population structure in sexually reproducing species is non-random mating between groups: if all individuals within a population mate randomly, then the allele frequencies should be similar … See more Population structure is a complex phenomenon and no single measure captures it entirely.
