Answer:

C. Gene trees are only useful studying the relationships of sequences from different species.

Explanation:

Gene tree traces the evolutionary history of a particular gene. It includes all the events like duplication and speciation. It helps to study the relationship of genes from different species. Often these are orthologous genes which came form the same ancestor and code for the same protein indifferent species. Gene tree also helps to study the relationship of genes in the same species. Often these are paralogous genes which evolved by duplication and code for similar but not identical proteins in the same species. Hence, the statement that gene trees are only useful for studying the relationships of sequences from different species is incorrect.

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

<h3>What is a gene? </h3>
  • 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.
<h3 /><h3 />

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.

1. How might the daily experiences of people contribute to their belief the earth and species do not change?
MariettaO [177]
People's daily experiences can contribute to their belief that earth/ species do not change because we are changing with it as it is happening. Also the changes happen gradually so you can't constantly see to believe it.
