Answer:
Occur in gametic (sex) cells
Explanation:
Mutated DNA sequences that can be passed from parent to offspring must be those that occur in gametic (sex) cells of the body.
Generally speaking, mutation refers to a sudden change to the DNA sequence of an organism's genome. It can be somatic when the changes occur in the somatic cells of the organism or germline when the changes occur in the sex cells of the body.
Somatic mutations cannot be passed to the offspring as the changes are not inherited by the offspring. However, a mutation that occurs in the germline of an organism can be passed to the offspring because the sex cells participated in fertilization and the formation of zygotes.
