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.

As i am asked to lead a research team to observe gorillas in their natural environment I will prefer a team having persons expert in having knowledge of forest in which we are doing research on gorillas. They must be experience in working with gorillas and familiar with their nature.

My team should have a person who know to use the tranquilizer gun because to collect the DNA sample gorilla needs to be tranquilized. My team should have one veterinary doctor who can examine the animal and take the DNA sample.

People with Good communication skills, observation skills and critical thinking skills are required in the team to successfully complete the research.
