Southern sea otters were thought to have been hunted to extinction in early 1900s. a group of fewer than 50 otters were discovered off the coast of central California in 1911. since then, the population has grown to 2800 individuals. Which statement most likely explains how the earlier reduction in genetic variation could affect the future of the southern sea otter? A. it could increase the ability of sea otters to find genetically different mates
B. It could reduce the causes of all types of mutations in the sea otter population.
C. It could increase the amount of competition for resources among the sea otters.
D. It could reduce the ability of the sea otter population to adapt to climate change.
