Somatic and gametic mutation

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. WebFor example, in humans, the average somatic mutation rate calculated from four tissue types was 17-fold higher than in the germline, 1.02 × 10 −9 /nt/cell division versus 0.6 × 10 −10. This somatic mutation rate is also higher (3.5-fold) than the average one in yeast and Escherichia coli [44].
