After reading this article we will learn about the Hardy-Weinberg equilibrium of gene. In a large random mating population, both gene and genotype frequencies remain constant from generation to generation, in absence of migration, mutation and selection. These properties of a population were first demonstrated by Hardy and Weinberg independently in 1908, and are generally known as Hardy-Weinberg law. If [...]
In this article we will discuss about:- 1. Selection of Disease Resistant Variants at the Plant Level 2. Selection in Vitro with Toxins and Culture Filtrates against Diseases 3. Selection for Resistance to Drought and Flooding 4. Selection for Salt Tolerance. Selection of Disease Resistant Variants at the Plant Level: One approach to utilise somaclonal variation is to screen regenerated [...]
In this article we will discuss about agarose gel electrophoresis. To know about quality and quantity of genomic DNA, agarose gel electrophoresis is performed on genomic and amplified DNA. Larger molecules migrate more slowly because of greater friction drag and they form their way through the pores of gel, less efficiently than smaller molecules. Range of separation in gel containing [...]
