WebA germline mutation, or germinal mutation, is any detectable variation within germ cells (cells that, when fully developed, become sperm and ova). Mutations in these cells are the only mutations that can be passed on to offspring, when either a mutated sperm or oocyte come together to form a zygote. After this fertilization event occurs, germ cells divide … WebAnswer (1 of 5): Variation is the same as mutation - a mistaken alteration of the correct arrangement for that species. It can be just accidental - a random fault in the genetics like wrong numbers of chromosomes or faulty chromosome construction, 'fragile X' for example - or it can be caused by...

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. Ver mais A germline mutation, or germinal mutation, is any detectable variation within germ cells (cells that, when fully developed, become sperm and ova). Mutations in these cells are the only mutations that can be passed on to offspring, … Ver mais Endogenous factors A germline mutation often arises due to endogenous factors, like errors in cellular replication and oxidative damage. This damage is rarely … Ver mais Many Mendelian disorders stem from dominant point mutations within genes, including cystic fibrosis, beta-thalassemia, sickle-cell anemia, … Ver mais Germline mutations can occur before fertilization and during various stages of zygote development.
