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 13. How will
the trait distribution most likely change over this time?

The plants having wide tips (trait A) retain the moisture, which means they are more prone to infection. So, the number of plants having trait A would be the most affected among all, and their number will significantly decrease, or may become extinct.

The plants having drip tips (trait B) drains away all the moisture, which means, they are less prone to fungal infections. So, the plants having drip tips would be the more abundant as compared to other traits.

The plant having mid-tip (trait C) retains a little amount of moisture. So, the plants having mid tip may or may not be infected, so, they can also survive, but the survival rate would be less than the drip-tip plants.

So, it can be concluded that plant having trait B would be most abundant in future, and plants having trait B would be less than plant having trait B, and the plant having trait A would either be extinct or least present.

In year one, Trait A has a medium-tip leaf, Trait B has a drip-tip leaf, and Trait C has a wide-tip leaf. I believe that Trait B is the neutral trait because it drains the water thoroughly. This can be bad if it doesn't get enough water for the plant to survive. Trait C is the harmful trait because it dosen't drain at all. This can be very harmful to the plant because if too much water builds up it could potentially get to the point where the plant has too much weight on it and it would snap off. Trait A is definetly the benifitial trait because it has a higher population, and it drains most of the water. Draining most of the water is good because it leave the little bit of water that the plant needs to survive. In year five, I predict that there will be a decrease in the population of the wide tip leaf because of the bad traits that they inherited. Trait B would have stayed the same, because they were thriving beforehand. Trait A would be doing great how it was before, and probably would have risen in population. In year 10, I feel like Trait C would have seen that they needed to change to survive, so it probably would have made the tips smaller so that the water could be drained. Trait B most likely didn't change much at all, and Trait A is probably still thriving with a bigger population than what it once had.

I hope this helps at least a little.
