Which of the following is NOT a consequence of selective pressure?

The process of natural selection involves selective pressures that favor certain traits over others, which leads to varying reproduction rates among individuals based on those traits. When selective pressure is applied, organisms with beneficial traits tend to have a higher survival and reproduction rate compared to those without such traits. This creates a situation where not all traits have equal reproduction rates—instead, traits that confer an advantage in a given environment become more common over generations.

As a result, the answer accurately identifies that equal reproduction rates for all traits do not occur under selective pressure. In practice, the traits that enhance survival and reproduction are likely to become more prevalent in the population, while less advantageous traits may decline. This unequal success in reproduction is a fundamental aspect of evolution, demonstrating how environments shape genetic variation and population dynamics.
