WebDNA Repair Genes. DNA replication itself and various types of DNA damaging agents can introduce errors into the genome. These errors include spontaneous mismatching of … WebGermline and somatic mutations. What determines if a mutation is inherited by offspring? Gametes cells arise from specialized cells called germline cells.Alternatively, the non-gamete cells within the body (muscle cells, neurons, epithelial cells, etc.) are called somatic cells.Therefore, when a mutation arises in a germline cell (germline mutation), the …
