Question

How does an environmental factor such as overfishing affect genetic factors in a population?
A. Overfishing will lead to increased genetic variation.
B. Environmental factors do not affect genetic factors.
C. Genetic traits that help fish survive are more likely to be seen in future generations.
D. Genetic traits that are targeted by the fishing industry are more likely to be seen in future generations.

Answer 1

Answer:

D.

Explanation:

Genetic traits that are targeted by the fishing industry are more likely to be seen in future generation

Answer 2

Answer:

Option C

Explanation:

The higher is the genetic diversity within a population of an organism, the higher will be the organisms ability to adapt itself in the changing environment. In case, the species of fishes which  are being over fished do not have sufficient number of individuals with varied genotype/allele for further mating, then the population and genetic diversity of that particular fish species would go down. However, the genetically stable species that could easily adapt themselves with in the changing environment or which have the ability to escape over fishing will maintain their genetic diversity and hence will survive easily.

Hence, option C is correct
