The population size of California sea lions was reduced to about a dozen in the early 20thcentury, primarily due to overhunting. The population size has since rebounded, and there are now thousands of sea lions. Which of the following would you notexpect to see in current populations of California sea lions? A. Considerable genetic polymorphismB. Very low levels of genetic variationC. Very few heterozygous individualsD. Differences in allele frequency between current populations of sea lions and historical populationsE. All the above would be seen in sea lions.

Abraham Juarez · Answer 1

a. Considerable genetic polymorphism.

Explanation:

In the increase of the new population of sea lions, there will be some differences among individuals, due to their genetic inheritance.

But since they come from the same group of ancestors and they reproduce in the same area, with the same environmental conditions, it is expected to be some genetic variations, but not a lot to be considerable.
