Genetic mutations are passed from parent to offspring by mutated gametes (sex cells) which are fuse to create offspring.
Further Explanation:
Sexual reproduction is the major method of reproduction in a variety of organisms. All the plants and animals majorly undergo sexual reproduction. The main process in sexual reproduction is:
Fertilization is a process of the fusion of gametes which are sperm and egg results in the diploid zygote. In meiosis ploidy level of germ cell get halved. Meiosis involves crossing over in between the non-sister chromatid of the homologous chromosome thus leads to genetic variation.
Germline or genetic mutations can be defined as the lasting change in the sequence of germ cell (sperm and ovum) DNA. These mutations can inherit from one generation to another. If a mutated gametes such as oocytes or sperm fuses with other. After fertilization, meiosis occurs and crossing over takes place which transfer the genetic information from parents to offspring. If the genetic information contains mutated gene that is also pass from parents to offspring.
