Question

In Wisconsin, a very large population of lake trout, in which individuals mate at random, experiences no migration, mutations, nor selective pressure for a number of years. Which of these is most likely to occur in the population? The frequency of dominant alleles will slowly increase. The gene pool of the population will remain relatively constant. The genetic variability of the population will slowly decrease. The frequency of dominant and recessive alleles will equalize.

Answer 1

The answer is the gene pool of the population will remain relatively constant. This is because the genetic pool available for mating is limited considering that there is no migration, mutation or selective pressure. In spite of the fact that mating is done continuously, the fact that they are done at random ensures that this mating remains comparatively constant. Even if variations may occur due to mixing of genetic material, the options available for this are also limited, thus maintaining a relatively stable genetic makeup for the population.

Answer 2

The gene pool of the population will remain relatively constant.
