WebOct 15, 2024 · What causes Gametic mutations? Exogenous factors Similar to somatic mutations, germline mutations can be caused by exposure to harmful substances, which damage the DNA of germ cells. This damage can then either be repaired perfectly, and no mutations will be present, or repaired imperfectly, resulting in a variety of mutations. WebDec 2, 2024 · If a gene is altered in a germ cell, the mutation is called germinal mutation. Germline tissue is set aside in the course of development to form sex cells. Germ cells gives rise to gametes, so if a mutant sex cell participates in the fertilization, then the mutation will be passed on to the next generation.

WebSomatic variation is the variation that takes place in the "somatic cells". While germinal variation is the variation that takes place in "germ cells" such as "eggs or sperms". Furthermore, mutation also can be agent in the genetic variation. Eukaryotic organisms have 2 primary cell types. Mutations can take place in either cell type.
