During natural selection, organisms with harmful traits are less
likely to successfully reproduce than organisms with beneficial
traits. Neutral traits don't improve or hurt an organism's chances
for survival. So, they tend to persist in populations when
environmental conditions are stable. If the environment changes,
neutral traits could become harmful or beneficial depending on
the situation.
In year 1, a population of rain forest plants has the following
distribution: 50% have medium-tip leaves, 25% have wide-tip
leaves, and 25% have drip-tip leaves. You will simulate three
years of this population: year 1, year 5, and year 10. How will the
trait distribution most likely change over this time?
