1. Which of the following events is not a source of genetic variation in eukaryotic organisms? J. Mutation
K. Independent assortment
L. Mitosis
M. Fertilisation

Mitosis

Explanation:

Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.
