In this article we will discuss about the principle of Hardy and Weinberg which requires five assumptions for explaining the equilibrium state of gene and genotype frequency. It was the year 1908, when an English mathematician — G. H. Hardy — and a German physician, W. Weinberg independently discovered the principle concerned with the frequency of alleles in a population, [...]
In this article we will discuss about:- 1. Meaning of Crossing Over 2. Frequency of Crossing Over 3. Factors 4. Molecular Mechanism. Meaning of Crossing Over: Crossing over may be defined as an interchange of corresponding chromosomal parts between members of a homologous chromosome resulting in a recombination of genes. One, two or more fragments may be interchanged during crossing [...]
In this article we will discuss about the analysis of the human genome. Molecular analyses of medical relevance rely heavily on four strategic features: (1) The ability to clone and characterize nucleic acid sequences, (2) The specificity of nucleic acid hybridization, (3) The specificity of restriction endonucleases, and (4) The power of DNA amplification using the polymerase chain reaction (PGR).
