Question

Which of the following statements is false?

Question 14 options:
a. Mutations do not occur in hox genes.
b. Hox genes that are found in different animals are very different from each other.
c. Hox genes control the normal development of an animal.
d. Hox genes occur in clusters.

Answer 1

Mutations can occur in hox genes, making this statement false.

Step-by-step explanation:

The false statement among the given options is a. Mutations do not occur in hox genes.

Hox genes are highly conserved genes that encode transcription factors and play a crucial role in determining the body plan and development of an animal. They are found in clusters and control the normal development of an animal. Although mutations can occur in hox genes, they are generally important for the proper development and organization of body segments and appendages. Therefore, the statement that mutations do not occur in hox genes is false.

Answer 2

The answer is; A

Hox genes in species are highly conserved. This, however, does not mean that mutations do not occur in hox genes. Rather, this is due to the disadvantage of mutation in this region. An individual with a mutation in the Hox gene is less likely to survive even past birth because of the significance of this gene to the development of the body.
