What are non inherited genes?

Non-inherited genes, also known as somatic mutations or acquired mutations, are changes in the DNA sequence that occur in non-germline cells during an individual's lifetime. These mutations can result from environmental factors, errors in DNA replication, or other cellular processes. Unlike inherited genes, which are passed down from parents to offspring, non-inherited genes are not transmitted to future generations. They can contribute to various health issues, including cancer, but are specific to the individual in which they arise.
