Verified step by step guidance1
Understand what a mutation is: A mutation is a change in the DNA sequence of an organism. Mutations can occur naturally or be induced by external factors such as radiation or chemicals.
Consider the types of cells where mutations can occur: Mutations can occur in both somatic cells (body cells) and germ cells (reproductive cells). Mutations in germ cells can be passed on to offspring, while those in somatic cells affect only the individual.
Explore the potential effects of mutations: Mutations can have a range of effects on an organism. They can be beneficial, neutral, or harmful, depending on the nature of the mutation and the environment.
Examine beneficial mutations: Some mutations can lead to beneficial adaptations, enhancing an organism's survival or reproduction. For example, a mutation might confer resistance to a disease or improve an organism's ability to utilize a resource.
Consider neutral and harmful mutations: Neutral mutations have no significant impact on an organism's phenotype, while harmful mutations can lead to diseases or malfunctions. The impact of a mutation depends on its location in the genome and the function of the affected gene.
