Question

what happens to advantageous traits within a population over many generations?
they disappear completely in the next generation.
they cause an organism to have fewer offspring.
they have no effect on the survival of the species.
they are passed to offspring and become more common over time.

Explanation:

To determine what happens to advantageous traits over generations, we analyze each option:

1. "They disappear completely in the next generation" is incorrect. Advantageous traits help survival/reproduction, so they don't vanish quickly.
2. "They cause an organism to have fewer offspring" is wrong. Advantageous traits typically increase reproductive success, leading to more offspring.
3. "They have no effect on the survival of the species" is incorrect. Advantageous traits enhance survival and reproduction, benefiting the species.
4. "They are passed to offspring and become more common over time" is correct. By natural selection, organisms with advantageous traits survive/reproduce better, passing the traits to offspring. Over generations, these traits increase in frequency as they improve fitness.

Answer:

The option "They are passed to offspring and become more common over time" (the fourth option in the list of choices).
