In biology and genetics, the germline in a multicellular organism is the population of its bodily cells that are so differentiated or segregated that in the usual processes of reproduction they may pass on their genetic material to the progeny. A germline mutation, or germinal mutation, is any detectable variation within germ cells 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 rapidly to produce all of the . Could a mutation in one of your liver cells ever be passed on to your children? The sequence of cells which develop into eggs and sperm.

Germline mutations are passed on from parents to offspring. This type of engineering is inheritable, meaning that the modified genes would appear not only in any children that resulted from the procedure, but in all succeeding generations. Typically gene transfer involves using a vector such as a virus to deliver a therapeutic gene to the appropriate target . Over recent years, there have been numerous insights into the regulatory mechanisms that govern both germ cell specification and the maintenance of the germline in adults.
