Role of DNA Mutations in the Production of Genetic Diversity Biology Essay
Mutations are sudden hereditary changes that occur due to abnormalities in the nucleotide sequence of DNA. A mutation is the source of genetic variation that affects the phenotype of crop species. Genetic diversity caused by mutations can have neutral, positive and negative effects on different characteristics of a plant species. Under these conditions, the high genetic diversity within the population will lead to variability, between different polymorphic sites, in the local mutation rates, which will further contribute to the increase of Genetic diversity affects biodiversity, and thus NCP, in two important ways: 1 by permanent genetic variation, that is, the specific combination of genes and alleles present at a given time. DNA sequence. Genetic variation. Germline variation and somatic mutation are closely linked and together shape human traits and disease risks. Germline variants are present from. Plant genetic diversity is a valuable resource for the production of food and other agricultural products. However, the loss of genetic resources is increasing at an astonishing rate, especially in the face of climate change. Induced mutation is one of the ways to generate genetic variation in plants that contributes to global food security; A key difference between gene editing and recombinant DNA lies in the nature of the genetic diversity being examined. Rather than mining gene bank collections or sifting through the genomes of other organisms, many efforts to expand genetic diversity with gene editing focus on "unlocking" the variation within a plant's own genome..
