Which environmental factor could lead to a decrease in genetic variation in a population of tuna?
jeyben [28]

Answer:

The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).

Explanation:

There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.

The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.

For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.

  • <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing </em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>
