The production of gemmae is a widespread means of asexual reproduction in both liverworts and mosses. In liverworts such as Marchantia, the flattened plant body or thallus is a haploid gametophyte with gemma cups scattered about its upper surface. The gemma cups are cup-like structures containing gemmae.
Genetic mutations are passed on because when the DNA is mutated, it stays that way. Therefor the mutated DNA would continue to be passed on because the same DNA is passed on to the offspring during meiosis, which produces gametes (eggs and sperm) mutations and all!
