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>

using the gas pedal analogy explain the impact on the cell cycle of a proto-oncogene versus an oncogene
rusak2 [61]

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.
