Answers

Genetic mutations are passed on because when the DNA is mutated, it stays that way. Therefor the mutated DNA would continue to be passed on because the same DNA is passed on to the offspring during meiosis, which produces gametes (eggs and sperm) mutations and all!

Answer from: trobbie817

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 microscopic organisms. It almost includes all the plants and animals. The main process in sexual reproduction is:

meiosis fertilization

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.

Germ line 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.
