Mutations in dna found in which cells are most likely to have significant evolutionary consequences?

Answer: Mutations in gamete cells.

Explanation:

Mutations in gamete cells, called germinal mutations, occurs in reproductive cells that fully develops to ovum and sperm. When a mutated sperm or egg cell (genetically altered) come together to form a zygote during fertilization, they pass down that mutation to their offspring and it stands a chance of being inherited by future generations. It is through random germinal mutations that evolution occurs.
