Which process can occur in both mitosis and meiosis? A. Crossing over
B. Gene mutation
C. Independent assortment
D. Fertilization

Mitosis and meiosis can both be influenced by mutation of genes.

Gene mutation refers to a change to the DNA sequence of organisms. Mutation can be of different kinds, including deletion, substitution, or insertion of base sequence into genes.

Gene mutation can happen during, before, or even after meiosis and mitosis.

B. Gene mutation

Explanation:

Stable changes in the DNA strand that are capable of being inherited are known as mutations.

The truly transcendent mutations for the offspring are those that are present or occur in germ cells (ovules and sperm).

The mutations that occur than can lead to small changes, large changes (causing disease: pathogenic mutations), or be silent.
