Question

Several companies now offer DNA "banking services," where DNA is extracted from a pet and is stored so that a "replacement pet" might be produced using cloning techniques when the original pet dies. Which statement best explains why the replacement pets that are produced in this way might not look or act like the original?

Answer 1

The question is incomplete. The statements are the following:

(1) The new animal must get the DNA from two different parents, not just one cell.

(2) Mutations could occur that change the cloned animal into a completely different species.

(3) Recombination of the cells as they are cloned will make the resulting pet act differently.

(4) The environment could influence how genes

are expressed, changing how the animal looks and acts.

Answer:

4. The environment could influence how genes  are expressed, changing how the animal looks and acts

Explanation:

An organism is product of the interaction between genes (inherited characters) and environment (non-inherited)
