Germline theory

WebIn plants, genetic changes in somatic lines can and do result in genetic changes in the germ lines, because the germ cells are produced by somatic cell lineages (vegetative meristems ), which may be old enough (many years) to have accumulated multiple mutations since seed germination, some of them subject to natural selection.

WebThe mutations of genes, proposed to occur over evolutionary time in the germ line theory, are postulated to take place within the lymphocytes of each individual of the species; i.e., each individual produces the necessary library of V region sequences de novo. WebHuman germline engineering is the process by which the genome of an individual is edited in such a way that the change is heritable. This is achieved through genetic alterations within the germ cells, or the reproductive cells, such as the egg and sperm.
