Mutations

Explanation:

The incorrect statements about mutation in the given question are:

-Mistakes in DNA replication do not lead to heritable mutations.

- Somatic mutations are often passed down to offspring.

Mutations are changes or alteration in the gene sequence of an organisms that may result in significant changes in the organism. mutation is considered as the basis for diversity. Mutations can be silent, lethal or beneficial. Mutations can arise from several sources like mistakes made during replication, translocation of chromosomal segments etc.
