WebMost mutations in organisms are deleterious by nature. This post explains this type of mutation in a comprehensive manner. Deleterious mutations do not persist in haploid populations, since they only possess one copy of genes, which if mutated, proves to be fatal to the organism. Thus, the mutated gene is not passed onto further generations. WebThe number of possible mutations induced in a gene by EMS can be predicted by its GC content (Harloff et al., 2012). Codon usage, therefore, could affect mutation frequency. In addition to physical and chemical methods, mutations can be induced in plants through the introduction of active transposable elements, such as mPing (Hancock et al., 2011).
