Microsatellites Currently, microsatellites (Box 74) are the most popular markers in livestock genetic characterization studies (Sunnucks, 2001). Similarly, this term encompasses various populations of one single species, like the different breeds of dogs or roses. 2.

Genetic Variation The measure of genetic differences existing within a population is called the genetic variation. It is generally recognized that plant genetic diversity changes in time and space. The diversity of the metabolome in plants arises from genomic evolution, genetic diversity, developmental stages, and environmental stimuli. Genetic Diversity Analysis. While the usefulness of molecular tools to describe genetic polymorphisms and the importance of generic resources in agriculture has been largely covered in the literature, we felt the need to highlight how the We were most pleased when Dr. Amir Muhammed, Vice Chancellor of the University of Agriculture, Lyallpur suggested that we hold a symposium on a topic of great importance to Pakistan, Genetic Control of Diversity in Plants, under the auspices of the University of Agriculture.

Also, plant populations that are less genetically diverse may be more susceptible, in some cases, to pathogens or other environmental stresses. and breeder-preferred traits (pest and disease resistance and photosensitivity, etc.). Following the works of Thomas Hunt Morgan and Hermann Muller in the 1910’s and 1920’s, plant breeders saw the value of physical and chemical mutagenesis for the production of new phenotypes. e assessment of EST-SSRs in genetic diversity analysis was done among plants belonging to distinct groups comprising cereals, Saccharum related genera, Saccharum species, and Saccharum cultivars.
