Answer:
Due to mutation.
Explanation:
Calix's cells having more DNA than a normal cat because of the change in the DNA due to exposure to chemicals or radiations. Mutation is the main cause for this more number of DNA than normal which occurs when the genetic material expose to X-rays or to ultraviolet radiation. Point mutation is a type of mutation in which one base pair in the DNA sequence is altered that leads to change in the DNA so we can say that mutation is the cause of this more number of DNA in Calix's cells.
