Question
Northern elephant seals population were hunted almost to extinction in the 1890’s. Their numbers were reduced to as few as 20 individuals at the end of the 19th century. Since then their population has rebounded, but their genes are all very close to being the same. All the following occurred in the Northern elephant seal population EXCEPT:

To provide an accurate answer, it's essential to clarify what kind of statements or options are typically provided in such contexts. The statement you are asking about involves the historical context of the Northern elephant seal population, their near extinction, and their genetic diversity.
The following scenarios might be typical in such a question:
1. The population rebounded significantly since the end of the 19th century.
2. Genetic diversity within the population is low due to the bottleneck effect caused by near extinction.
3. The population is thriving on the west coast of North America.
4. The seals have developed entirely different genetic traits post-recovery.
The correct choice for "all the following occurred in the Northern elephant seal population EXCEPT" would typically be the statement that misrepresents the outcomes of the population recovery or their genetic situation. In this case, it would be option 4: "The seals have developed entirely different genetic traits post-recovery," as the low genetic diversity due to the historical bottleneck means that the seals have not developed significantly different genetic traits.
Thus, you could specify that changes in genetic traits have been minimal due to their lack of genetic diversity.
