In the past century, sea otters in the California coast have been hunted to almost extinction. Nowadays, few populations remain. As a biologist, your job is propose a plan to help maintain healthy populations of otters. The initial step, however, is to identify any signs of inbreeding (i.e., non-random mating) in the existing two populations, so you can better manage them. Here is what you know about a particular locus (A) that you are using in your genotyping studies:

- Santa Cruz population: 54 otters

Genotypes: 26 otters (AA); 7 otters (Aa); 21 otters (aa)

- Monterey population: 174 otters

Genotypes: 50 otters (AA); 79 otters (Aa); 45 otters (aa)

Are these populations inbreeding? How can you tell? What can be the potential evolutionary mechanisms acting in these populations, and why? What would you proposed to better manage these otter populations?
