External factors such as radiation and chemicals can cause mutations throughout genes and chromosomes. For a mutation to be passed on to offspring, it must occur in the sex cell.

What are mutations, its types and causes?

Changes to the DNA sequence are known as mutations. Types of mutation include: Chromosome change. Point mutation. Frameshift mutation. Viral infection, exposure to mutagens, and mistakes in DNA replication during cell division can all cause mutations. Germline mutations (occurring in oocytes and sperm) can be passed on to offspring, whereas somatic mutations (occurring in somatic cells) are not.

Are mutations good or bad?

Mutation effects can be beneficial, harmful, or neutral, depending on the situation and location. Most non-neutral mutations are harmful. In general, the more base pairs affected by a mutation, the greater the effect of the mutation and the more likely it is to be deleterious.
