1. Natural selection is the best of the organisms to live past hardships and survive, leaving the weakest to die. Survival of the fittest.

2. Adaptation is an organism changing to better themselves in a certain environment.

3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.

4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.

5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.

6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.

7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.

Given our understanding of genetics, we can confirm that the gene in question is of the homeotic type.

In biology, we refer to a gene as the most basic unit of genetic information.
It is a segment of DNA that encodes for a certain trait that <u>may or may not be expressed.</u>
A gene carries the information for a specific trait, for example:

1) Eye color

2) Body organization

3) Height

<h3 /><h3 /><h3>What does it mean for a gene to be homeotic?</h3>

In the case of this question, the gene in question is a homeotic gene.
Homeotic genes are those that are in charge of the organization of the organism's body.
These genes control the <u>general pattern of the body</u>, such as where the arms and legs will be, and so on.

Therefore, given the definition of a homeotic gene, we can confirm that this is the type that best fits the description of the mutation in the question since it affected the formation and normal organization of the body.
