Question

Answer 1

Answer:

Exposure to chemical or radiation.

Explanation:

Mutation in a gene can arise during meiosis due to exposure to chemical or radiation that cause change in the genes. After this change in DNA, the meiosis cell division produces gametes that can be passed to the offspring and contribute to genetic variability of the organism. Meiosis occurs in the sex cells which can be transferred from parents to offspring.
