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.

WebIn plant breeding, the induction and identification of seed mutations is a simple process. Once the mutant population is obtained and the mutation is identified, seeds from the mutant plant compose the next generation in which the phenotype will be analyzed in order to search for mutation effects ( Henry et al., 2014) ( Figure 2 ). FIGURE 2 WebMutation refers to any change in the sequence of Nucleotides in DNA, which leads to changes in the genotype and phenotype of an organism. Mutations can be induced or spontaneous. Mutations can either be beneficial or harmful. Mutations lead to variation, which is one of the driving forces of evolution.
